where the origin of the angle θ is taken at the leading point.

The pressure coefficients are therefore:

Cp=1 at the leading point.

Cp=-1.25 at the top point.

The error decreases with the number of surface elements:

where the origin of the angle θ is taken at the leading point.

The pressure coefficients are therefore:

Cp=1 at the leading point.

Cp=-3 at the top point.

- All three methods give good precision for mesh sizes greater than 1000 elements.
- The linear triangular order method converges faster and is slighty more precise in the case of the sphere.
- The uniform triangular method is slightly more precise in the case of the cylinder.
- The use of the linear method does not seem to be justified with regard to its added complexity and the longer analysis times vs. the low benefit in Cp precision.
