Abstract

A novel level set Immersed Boundary method is used for transient Computational Fluid Dynamics simulation of flow across a moving/rigid Immersed boundary. At various time instants level-set is used to capture moving boundaries accurately with proper numerical implementation of boundary conditions and conservation laws in fluid regions. An in-house code is used to study four different problems ranging from a flow over a stationary circular cylinder, a rotating circular cylinder, pitching of airfoil and an undulating swimming fish-like undulating body with amplitude variations.
