Can coefficient of drag value be as large as 14?
 

Hi people,
I am new to Ansys Fluent, currently I am simulating the re-entry of a space module with following free stream conditions.

1. Inlet Mach number = 6
2. static pressure = 554.113 Pa
3. static temperature = 237.218 K

The data corresponds to atmospheric condition at an altitude of 35 km. The simulation I am doing is steady state. When residuals converge to value below 1e-03, I got coefficient of drag around 14. The reference conditions used for calculating the drag coefficient are:


1. Area = 1 m^2
2. Velocity = 1853.159 m/s

3. Density = 0.008137 kg/m^3

Can somebody tell me, is this value of drag coefficient is acceptable?

Is it right to use 1 m^2 for the reference area?

Thank you sir! The area should be frontal area of the module.
