Abstract

In the present study the effect of air swirl on the combustion characteristics and pollutant emission of biodiesel B5, B10 and gasoil combustion is studied. The experiments are carried out on an axisymmetric cylindrical combustion chamber. Numerical investigation is conducted using fluent computer code. The RNG, k-&epsilon model is used for the modelling of the turbulence phenomena in the combustion chamber. The eddy dissipation model is used for the simulation of transport combustion. The experimental and numerical result show that the exhaust gas temperature, the levels of NO_x and CO₂ emission increase with increase of swirl number and then decrease. The CO emission declines with increase of swirl number. The numerical and experimental results are in good agreement.
