Body force in fluid mechanics
Web4. Examples Example: Settling Velocity of a Sphere Q: After a body is released in a fluid which is less dense than the body, it will accelerate downwards until its buoyant weight is balanced by the drag force which opposes the motion. The constant velocity at which the body is falling is the terminal or fall or settling velocity. 1. Consider a 10 mm diameter, … Web2 Governing Equations of Fluid Dynamics 19 Fig. 2.2 Fluid element moving in the flow field—illustration for the substantial derivative At time t 1, the fluid element is located at point 1 in Fig. 2.2. At this point and time, the density of the fluid element is ρ 1 =ρ(x 1,y 1,z 1,t 1) At a later time, t

Websubject to body torques, as in magnetic fluids. In case of a polar fluid we must introduce a body torque per unit mass in addition to the body force and a couple stress in addition to the normal stress t (n). The stress for polar fluids is discussed by Aris. A fluid is nonpolar if the torques within it arise only as the moments of direct forces. WebConsider a small fluid element of dimensions dx, dy, and dz as a free body diagram, on which all forces acting on the element will be discussed. There are three kinds of forces …
