3d Compressible Melt Transport with Mesh Adaptivity

Melt generation and migration are important processes for the evolution of the Earth’s interior and impact the global convection of the mantle. While they have been the subject of numerous investigations, the typical time and lengthscales of melt transport are vastly different from global mantle convection, which determines where melt is generated. This makes it difficult to study mantle convec...

An Alternating Direction Implicit Method for Modeling of Fluid Flow

This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...

Multi-Body Flow Field Calculations with Overlapping-Mesh Method

An efficient overlapping-mesh method for Euler flow solvers is developed and applied to two-body flow field problems. It features simple procedures to determine the interface cells on which the flow quantities are to be transferred from one mesh system to the other. This allows a great flexibility of mesh arrangements. The method is applied to two cases; one is the transonic flow field around v...
