Initial layer thickness
Webb3 sep. 2024 · The effect of an initial boundary layer thickness on the turbulent flow over a backward-facing step is investigated by using large eddy simulations. Three different initial boundary layer thickness, \delta /h = 0.26, 0.5, 1.2 and three different Reynolds numbers, {\text {Re}} = 5,100, 24,000 and 45,000 are considered. Expansion ratio is 1.2. WebbIf you’re using a .4mm (0.015 in) nozzle, you should choose a 0.20mm (0.009 in) initial layer for best results. However, some materials such as PETG may require a higher initial layer.
