combustion chamber

One of the most crucial sciences in automobile, space, and aerial industrial is related to combustion and reaction science. The internal combustion engine of automobile burn gasoline (C8H18) and heat released from this combustion caused the temperature of reactant reached about 2138 and based on ideal gas approximation the volume of reactant reach about seven times of primary volume (constant pressure) or pressure reaches about seven times (constant volume). Increasing pressure and volume of gases leads to piston movement. The philosophy of combustion in jet engine combustion chamber is a bit different. The main target from burning of JP4 (Keresan-gasoline blend) is increasing in volume of product and in constant area of jet tube predicting velocity should be increased. Although some combustion energy derived to rotate the turbine.  The thrust of jet is directly related to velocity (thrust is equal to mass flow rate multiplied by velocity).  Combustion is science of reaction of hydrocarbons the concentration of product and heat released.combustion chamber

We are experienced in the field of computational fluid dynamic simulation of combustion. You can see a summary of our experience in CFD simulation of combustion in portfolio in our website. The first simulation we have done is related to simulation of combustion in combustion chamber of jet engine, two strokes and 4 stroke engine. The type of combustion simulation in jet engine and two-stroke and 4 stroke is different. In jet engine combustion chamber, we use eddy-dissipation model for modeling turbulent chemistry reaction. Because we know the nature of this reaction, simulation is steady and rate of reaction is not very important. We simulate an infinite reaction rate. In the other word when reactant (hydrocarbons fuel and oxygen) reach each other the reaction will start. But in internal combustion engine, especially for automobile, time of reaction is crucial and could not simulate by eddy dissipation model. The rate of reaction is infinite will calculate using Arrhenius model and we use spark ignition model to control the time of combustion. By using spark, we prepare the needed activation energy of this reaction. The magnitude of spark energy and location of spark is significant for controlling the reaction time and shape.combustion chamber

The main parameters we investigate in designing combustion chambers is the effect of equivalence ratio and direct and magnitude of velocity on combustion performance. The equivalence ratio is the ratio of air/fuel stoichiometric to air/fuel actual, and if this ratio is below than one, the mixture is lean and if this magnitude is higher than one the mixture is rich. This is just theory of being rich or lean. If mixing does not perform well maybe we have rich mixture although we have rich mixture in the paper. Well mixing is critical and we use various method for this purpose. Using vortex generator, using fan for increasing turbulence and using tangential air injection in cylindrical chamber for increasing residence time reactant and increasing turbulence is some of these methods.

Also changing velocity in constant equivalence ratio is an essential factor. Velocity magnitude and direction will control the residence time and turbulence intensity and finally the affect on combustion performance.

Some of the experience in the area of combustion simulation can be seen in the following

  • combustion in annular, can annular, can and double annular combustor
  • CFD simulation of CH4 (methane) combustion in a vortex flame chamber
  • Simulation of two and four-stroke engine in internal combustion engine using dynamic mesh methodcombustion chamber
  • Combustion and explosion of methane in a circular tube
  • Combustion of Keresan in a gas turbine combustion chamber
  • Methane combustion in a vortex flame chamber
