Webstreamlined and thin, and their drag also is primarily from skin friction, except when the angle of attack is high and the flow is separated. Bluff bodies are not streamlined, and … The force between a fluid and a body, when there is relative motion, can only be transmitted by normal pressure and tangential friction stresses. So, for the whole body, the drag part of the force, which is in-line with the approaching fluid motion, is composed of frictional drag (viscous drag) and pressure drag (form drag). The total drag and component drag forces can be related as follows:
WebIn aerodynamics, a bluff body is one which has a length in the flow direction close or equal to. that perpendicular to the flow direction. This spawns the characteristic that the …
WebApr 3, 2012 · Shock impingement, or interference, refers to a flow where an oblique shock impinges on the upstream portion of a blunt-body shock wave (Edney, 1968).The interaction is fundamentally different from that shown in Fig. 3.1.11.
