Level Set with Adaptive Mesh Refinment for Computing Complicated Flows


Computing flows over bodies of complex shapes is challenging especially if the bodies are in motion. We are implementing a Cartesian Block-Based Adaptive mesh technique for solving compressible Navier Stokes equation to compute flows over complex moving objects. The boundary of the complex body is represented implicitly by a level-set. An object-oriented code is being developed for this problem using the hierarchical adaptive mesh CHOMBO library developed at Lawrence Berkeley National Laboratory. The mesh adaptation allows for higher fidelity representation of the complex boundary between the fluid and the solid as well as good resolution of the flow features.
