Computational Fluid Dynamics Based on the Method of Space-Time Conservation Element and Solution Element

Abstract


The space-time conservation element and solution element (CE/SE) method will be introduced. Computational results of some general fluid dynamic, aeroacoustic, and combustion problems will be presented to demonstrate its high accuracy and robustness. The CE/SE method is a new numerical method for solving the conservation laws. It is substantially different in both concept and methodology from the traditional methods, such as finite-difference, finite volume, and finite element methods. It is constructed based on the flux conservation in space and time without using dimensional-splitting approach. It is genuinely multidimensional and compatible with unstructured meshes. Numerical applications to be presented are summarized as: (1) Complex wave patterns including shock waves and its reflection and interaction with bodies and other waves using both structured and unstructured grids. (2) Aeroacoustics (turbomachinery noise, jet noise, etc.). (3) Combustion and chemical reaction. (4) Steady and unsteady flowfield in different speed ranges (subsonic, transonic, and supersonic) in both internal and external configurations.
