摘要：

Experimental and numerical studies of combustion process in a vortex flow device have been developed. The modelling part of the study has been performed by means of ANSYS Fluent package. Fuel droplet trajectories and the flow pattern on their motions have been modeled by the function "injection". The combustion process utilized the k-epsilon turbulence model. A special trend on the effect of the vortex generator blade orientation on the gross process has been developed. It has been established that optimal process performance (high air excess ratio and low NOx emissions) could be attained with an angle of the vortex generator blade orientation, especially with respect to the minimization of NOx emissions.
