Abstract [eng] This project presents liquid droplet heat and mass transfer intensity in combustion products. Methodology of the „droplet” problem solution was examined. Then particular heat transfer, condensation and evaporation problem solved where water drops were sprayed in the combustion products which is directly related with droplet and its surrounding calculations in wide range of temperatures. Influence of boundary conditions to heat transfer and evaporation intensity is shown. Numerical heat and mass transfer experiments were conducted for each group with four different sizes of droplet with cases of heat transfer by convection. For this numerical experiment program called „the drop” was used created by Kaunas University of Technology Department of Thermal and Nuclear energy. Results were graphically analyzed and described. Accuracy of the applied method was evaluated with energy fluxes imbalance diagrams and conclusions were made to enhance heat and mass transfer intensity depends on droplet dispersity, surrounding temperature and heat transfer method.
