 Numerical calculation of turbulent reacting flow

The process of combustion, i.e. the process in which chemical components at stongly exothermal (heat releasing) conditions are oxidised, in most technically relevant applications ist used to convert energy but also to convert mass (e.g. to convert pollutants or poisonous matters) or in a combination of both.

Beneath the (wanted) goals combustion also plays an unwanted role in the context of emission of pollutants (e.g  nitrogen oxides, carbon monoxide, carbon dioxide, sulfur dioxide, ultra fine particlates) and invironmentally harmful release of heat  Additionally there is another area of concern based on the fact that useable fossile fuels are limited and the widely accepted fact that combustion products (especially CO2) negatively influence the world climate: therefore search and investigation on the use of alternative, renewable fuels have come into focus in the last decades. 

 

Model systems

Research in the area of combustion technology starts by looking at the basic physico-chemical processes:

  • convective transport of matter and energy by flow,
  • diffusive transport of matter and energy by the molucular motion and heat transmission by radiation and
  • conversion of chemicel species by chemical reaction.

A simple example that shows the effect that the intensity of these single processes have on the overall phenomenon "flame" ist the so-called laminar, premixed flame. As the components fuel and air have been already mixed here before the chemical reaction, the the transport processes of energy are the most controlling processes, here:

     
Laminar methane-air flames at different equivalence ratio (air excess); the right picture shows streak lines of such a configuration (schematically)

In this picture laminar methane flames are depicted that emerge from different ratios of fuel (methane) to air. A significant difference in the length of the flames despite the fact that all flames form on top of the same velocity of the mixture flow emerging the supply pipe. From this it can be concluded that the chemical reaction takes place at different "speed". 

Additionally to the flames shown above, that are stabilizing above a nozzle, there are also other configurations at which a stationary flame, i.e. a flame that is fixed at one point in space, evolve: an example are the counter flow premixed twin flames:

    
Schematic of laminar, premixed, twin counterflow flames

Here, two premixed fuel/air jets are positioned apposing each other (in the picture from top and bottom), so that a flow field forms that has a stagnation plane (velocity along the axis is zero) and which allows only radial outflow of the gases. If the premixed gas flows have been ignited two premixed flames evolve in the strongly diverging flow field. The flow divergence is the reason why this configuration is very interesting for combustion scientists. It is possible to control the strain rate of the flow field by simply adjusting the incoming fluild velocity and so to investigate the the interaction of flame and its stretching by the flow field. This is especially of interest because flames most often are applied in a flow field that is turbulent where high strain rates can be expected.

    
Schematic of laminar, counterflow diffusion flame

In contrast to the already mentioned premixed flames, in technical Applications usually non-premixed flames are engaged due to security issues. Such a flame forms, if the fuel and oxidator (usually air) is not already pre-mixed by some upstream device but both enter the combustion chamber non-premixed. This means that before the chemical reaction can start the mixing of oxidizer and fuel has to be done at the same place. As chemical reactions in many situations are much faster than the mixing processes, the chemistry has to "wait" apon mixing, a situation that is called mixing controlled, which means that the speed of reactive conversion is given by the speed of the mixing process. As in laminar flows mixing is provided by the molecular transport of species -i.e. by diffusion- such flames are also called diffusion flames in the german language. Examples of non-premixed flames are candle flames or flames that form in an counterflow diffusion burner. In the latter it is possible by controling the volume flows of fuel and air to form scientifically controlled conditions in order to investigate the interaction of stretch and local air excess ratio. 

 

Turbulent flames

In technical applications the flow rates are required to be much higher - compared to the examples above - and therefore, also large scales and/or high flow velocities are a consequence. Due to the imposed larger Reynolds number. such flows are not as regular as in laminar flows, but rather irregualar and due to flow instabilities also non-stationary. Such flows are called turbulent and are locally changing quite fast. Despite of this irregularity, in many situations a turbulent flow is characterized by the fact that time averaged values of the flow velocity exist, so that it may be called stationary in a statistical sense. The average of the instantatious deviation from the mean value itself can be used as a measure for a so-called turbulent diffusion, so that the average flow field may be regarded like a rather viscous/diffusive version of a laminar flow. For combustion the enhanced, "turbulent" diffusion is beneficial insofar as it provides enough speed for the mixing of fuel and oxidizer to enable the necessary high conversion rates for industrial applications.

For the design and lay-out of a technical process there is a need to be able to make reliable predictions about the consequences that specific changes in the system or of the process parameters impose on quality an amount of the products of the process. In order to make such predictions, usually extensive and constly experiments have to be conducted in lab and pilot plant scale.

 


Test rig for investigations in highly turbulent flames

 

With regard to the reduction of pollutant emissions, experiments are performed also at facilities that are under operation but in most cases in lab scale test rigs. As a result many, strategies have been already developed in the last decades that enable to reduce pollutants, such as NOX. Deeper insight into the details of pollutant formation still is only partly possible because of the limitations that are imposed by diagnostics. As a major reason for such limitations the high temperatures occuring in relevant combustion systems (1000-2000 °C) may be mentioned.
 

Numerical Simulation

Additionally to experiments, numerical simulations have become an important and valuable tool to validate the current concepts of the interaction of the several processes involved in the overall phenomenon "flame": Carrying out simulations built upon these ideas gives the opportunity by comparison with the observable quantities of measurements to test the concepts that are supposed. Moreover, for a limited range of application by now it is already possible to predict flames that result from given geometries and operational conditions.

Numerical simulations base on well known equations for the balance of physico-chemical quantities like mass, momentum, mass fractions of species, and energy. For simple systems these balances can be solved directly in an analytical way. If the system becomes more complex such a solution is not known by analytics but there exist algoritms that enable to calculate an intermediate solution based on a previous guess that in turn, forms a better guess. This means, that by subsequent application of the algorithm a reasonable accurate guess can be achieved. Using computing devices, this gives the opportunity to approximate the solution of the equation system (the model) consecutively and in a reasonable calculation time. For such algorithms to be used with computing devices the equations and the space where the quantities need to be known need to be discretized (leading to algebraic equations with discrete numbers instead of functions and differentials).

The quality of the result strongly depends on the pre-requisite that all contributing processes are appropriately resolved in space and time, i.e.that the length and time scales of all processes need to be resolved properly; a fact which imposes a large effort to be taken depending on the range of length and time scales involved. If the effort for direct simulation becomes too big (which is usually the case) then additional models, describing the effect imposed by "coarsening" the resolved scales come into play.

Neben experimentellen Untersuchungen werden aber auch immer häufiger Vorhersagen mit computergestütztern numerischen Simulationen verwendet, um Anlagen möglichst optimal auszulegen. Mit numerischen Berechnungsverfahren können Gleichungssysteme, die nicht direkt (analytisch) gelöst werden können, durch die Anwendung eines mathematischen Algorithmus zumindest näherungsweise berechnet werden. Damit ist eine relativ einfache und kostengünstige Möglichkeit gegeben, Brenner und Brennraumgeometrie zu variieren und so schon im Vorfeld den Einfluß konstruktiver Maßnahmen zu untersuchen und direkte Einsicht in Detailvorgänge, wie z. B. die Turbulenzstruktur oder turbulente Fluktuation von Einflußgrößen des Bildungsprozesses zu nehmen.

Die Vorhersagequalität solcher Simulationen ist aber durch die Vielzahl der beteiligten physikalisch-chemischen Teilprozesse und deren komplizierter Wechselwirkung auch heute noch nicht befriedigend. Sie hängt stark von der Qualität der Modellvorstellungen für die Einzelprozesse und vor allem auch von den Modellen, die deren Zusammenwirken beschreiben, ab. Die Erstellung solcher anwendungsrelevanter Modelle stellt daher einen Hauptschwerpunkt der an diesem Institut durchgeführten Untersuchungen dar.
