Conversion of solid reacting particles in a non-premixed double shear layer

As the increasing the efficiency of the combustion processes is crucial nowadays, a fundamental understanding of this process is required. This thesis is focusing on the effect of turbulence on the conversion rate of solid reacting particles in non-premixed mode. The DNS tool, the Pencil-Code is used to simulate a double shear jet with reacting particles, in order to resolve the smallest scales of the fluid flow. In this study, the reaction rate turned out to not to change linearly with increasing number of particles. The results showed that for Stokes number equal to 0.35 the particles created the sharpest clusters affecting the reaction rate. The necessity of future work on the subject is underlined, i.e. implementation of the realistic chemistry of the combustion process, further analysis for increasing number of particles and performing presented simulations with a different method such as LES, in order to compare the results and computational cost to the accuracy of the results ratio.
