Witryna12 kwi 2024 · He, “ A smoothing technique for discrete delta functions with application to immersed boundary method in moving boundary simulations,” J. Comput. Phys. Phys. 228 , 7821 (2009). 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…
