WebMay 11, 2011 · Total (or ram) pressure is the pressure a fluid exerts as it is brought to a stop. Total pressure is what acts on you as you face into the wind and the air collides with your body. Dynamic pressure is the pressure of a fluid that results from its motion. It is the difference between the total pressure and static pressure. WebTurbulence free-stream boundary conditions. In most CFD simulations it is necessary to specify values of the turbulence variables at the inlets. For example, if you are using a model you have to specify values of and at the inlets. This is often difficult and a source of uncertainty since the incoming turbulence is rarely known exactly.

Webwhere q is the free stream dynamic pressure, D is the total drag measured by the balance, A is cross-sectional area of the body, pB is base pressure, pa is static pressure of the ambient free stream. From Figs. 45 and 46 it may be seen that the influence of spike length on the drag is qualitatively similar for both shapes and for all Mach numbers.
