Spring 1999 Seminar Series
Computational Fluid Dynamics Based on the Method of Space-Time
Conservation Element and Solution Element
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.
