WebMar 2, 2024 · As a non-streamline body, bluff body is widely applied in many engineering projects such as aerospace, construction, transportation, and environment, which has a larger and even more overwhelming differential pressure resistance compared to streamlines in case of aircraft, building structures, bridges, automobiles, heat exchangers, … 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:
