velocity inlet turbulence, specification method for sedan geometry on wind tunel,,turbulenct intensiity value and turbulent length scale for value at velocity inlet?how much i predict this value??
and the outlet??? please help... |

Prowide us with some more detailed data. What type of wind tunel is this? What is air speed. Turbulence modeling is always very baffling.

i use the bmw 320i sedan for my basic geometry,the valid Cd is 0,26, i want use viscous model k-omega SST,,velocity magnitud 25-30 m/s.. area = 2.08 m2, length wind tunel = 23.32 m, turbulence specification method = intensity and length scale,,but i don't know the value T I and Length scale must i predict..to get Cd 0,26,, and than i redesign the sedan geometry for get optimal value Cd,,this for my thesis,,please help...
