Adaptive Meshing of Ship Air-Wake Flowfields

Abstract

The objective of the proposed research is to deliver enhanced mesh adaptation capabilities that account for the chaotic unsteady nature of the flowfield in the landing approach path. The research will explore three distinct meshing methods to handle the dynamic aspect of this case. The three methods include a hierarchical Cartesian hexahedral method, an all-tetrahedral mesh method and a physics-based point placement meshless method. The initial phase of the research will develop pseudo-steady analysis procedures for each method, with appropriate mesh adaptation capabilities. The goal of the research is to compare and contrast the adaptive meshing technologies of the three approaches.
