Drag

Description

Drag is a resistive force opposing an object’s motion through a fluid, resulting from surface pressure and shear forces. It comprises two components: a perpendicular one from pressure and a tangential one from shear stress. Accurate drag calculations use pressure and wall shear stress distributions, often determined thro...

Transcript

Drag is a force that resists an object's motion through a fluid caused by pressure and shear forces on its surface. It has two main components: friction drag and pressure drag.

Friction drag results from shear stress on the surface, depending on wall sh...
