How to Evaluate Drag Force for Bluff Bodies?

Drag Force for Bluff Bodies evaluator uses Drag Force = (Drag Coefficient*Frontal Area*Density of Fluid*(Free Stream Velocity^2))/2 to evaluate the Drag Force, The Drag Force for Bluff Bodies formula is defined as the function of Drag force, frontal area, density of fluid and free stream velocity. The force exerted on a solid body moving in relation to a fluid by the fluid's movement is known as a drag force. For instance, drag on a moving ship or drag on a flying jet. As a result, a drag force is a resistance created by a body moving through a fluid such as water or air. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag. It makes no difference whether the object moves through a static fluid or whether the fluid moves past a static solid object. Drag Force is denoted by F_D symbol.

How to evaluate Drag Force for Bluff Bodies using this online evaluator? To use this online evaluator for Drag Force for Bluff Bodies, enter Drag Coefficient (C_D), Frontal Area (A), Density of Fluid (ρ_Fluid) & Free Stream Velocity (u_∞) and hit the calculate button.
