Truck Aerodynamic Simulation
 
Hi all,

I am working on a truck simulation and the objective is to reduce the drag coefficient with various types of drag reduction device. But the result i get from my simulation is not desirable which is 0.03 when compare with my journal's result 0.6.

I used AutoCad Inventor to draw the model and convert it to .SAT format in order to be used in ANSYS Fluent. The flow is turbulence and the model is an empty design.

Anyone of you did this before? I need to know the boundary conditions, such as the turbulance intensity.

Any information i should provide for further understanding?

Thx in advance.
