WebThe IB method represents the moving boundary using Lagrangian markers at which force-densities are computed, based on the position of the membrane, and spread to Cartesian uid grids by a set of discrete delta functions. The support of the delta function here is comparable to the mesh width. WebNov 21, 2015 · First of all, the immersed boundary method is a mathematical model that describes elastic structures (or membranes) interacting with fluid flows. For instance, the blood flows in a heart can be considered as a Newtonian fluid governed by the Navier-Stokes equations
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…
