In computational fluid dynamics, the immersed boundary method originally referred to an approach developed by Charles Peskin in 1972 to simulate fluid-structure (fiber) interactions. Treating the coupling of the structure deformations and the fluid flow poses a number of challenging problems for numerical simulations (the elastic boundary changes the flow of the fluid and the fluid moves the elastic boundary simultaneously). In the immersed boundary method the fluid is represente… Witryna12 wrz 2016 · Stability of Immersed Bodies The stability of an immersed body depends on the relative locations of the center of gravity G of the body and the center of buoyancy B that is the centroid of the displaced volume*. a) The body is stable if the body is bottom - heady (G below B); A disturbance produces restoring moment to return the …
