Direct Numerical Simulation of Primary Breakup Phenomena in Liquid Sheets

摘要: Starting from the first experimental and analytical studies on primary breakup phenomena, many interesting results have been published in past. It is known that addition to typical dimensionless groups (Reynolds Weber number), inflow conditions can drastically influence phenomena. Now high computational resources are available, direct numerical simulation (DNS) has become a powerful tool order study Nevertheless only few DNS concerning phenomena of available. This might be due fact besides demands resources, sophisticated models also required prescribe realistic capture all length scales flow. paper mainly focuses different conditions, such as integral scale or fluctuation level inside turbulent nozzle For this, water sheets at moderate Reynolds numbers injected into an quiescent air environment considered. Since this performed experiment by varying character velocity data, it was found not mean axial profile but
