Shiuh-Hwa Shyu

How erroneous?

Bharath Ram Ravi

Thank u for ur replies,

Mr Aziz we used the default wall model available in ANSYS Fluent. I cant understand what u mean by adverse pressure effects.

Mr Shiuh-Hwa Shyu deviation from experimental value is more than 50%.

We are doing analysis for varying angle of attacks. For higher angle of attacks like 10 degree there is a significant separation. But the Cd values are varying for all angle of attacks.

Thank You Aziz. I will look into the near wall model.
