Pressure Coefficient in X - Direction -- CFD Online Discussion Forums

April 6, 2007, 21:43	Pressure Coefficient in X - Direction	#1
Matthias Guest Posts: n/a	What is the relationship to calculate the static pressure in the x direction (assuming x,y, dimensions)? I wish to contour plot Cpx to visualise sources of pressure drag more effectively. Would the pressure in the x direction be... Px = (Total pressure) - (0.5densityX-Component_velocity^2) Then Cpx = (Px - Pref)/qref Could someone please clarify how to go about obtaining x-direction pressure coefficients.
