Abstract

Space-time conservation element and solution element (CESE) method is a unique finite-volume-type method for computational fluid dynamics (CFD). This approach has several attractive properties, including: (i) unified treatment of the space and time such that only one step is required to construct high-order schemes; (ii) a highly compact stencil regardless of the order of the accuracy; (iii) easiness of extension to any arbitrary shape of polygonal elements. Since its inception, the CESE method has achieved great success in different areas. This seminar will first introduce the basic concept of the CESE method. Then, some advanced development of the CESE method will be presented, including positivity-preserving schemes, high-order schemes and moving-mesh schemes. Finally, some CFD examples (including hypersonic non-equilibrium flows, compressible multicomponent flows, and detonation waves) will be shown.
