Hi Brothers/Sisters, I need to analyse and to find Coefficient of drag and lift (CD and CL) for the scaled sedan car moden by using ANSYS-FLUENT (K-Epsilon) Model. The dimensional details of the car model are follows length 460mm, width 160mm and height 140mm which is placed inside the computational domain dimensions are follows as length of 9 times the car length (i.e) 4140mm and width of 1380mm and height of 1150mm. My query is in order to determine turbulent length scale (l=0.07L) where l=turb.length scale and L=chracteristic length
Q.1 For this L, whether I need to use model car model length or computational domain length. Q.2 How to calculate Hydraulic dia whether Hyd=(4A/P) is right of wrong for this case. Q.3 Please suggest any other methods to find CD and CL for the car model. Q.4 How to calculate turb intensity and turb dissipation rate. Q.5 Whether in solution controls i need to select compute from inlet zone or front of the model zone. I am expecting all your golden reviews in my blog, please guide and reply me to solve this problem and thanks in advance. Last edited by gshankarau; September 29, 2016 at 03:38.
