Opis

Practical fluid flows are often associated withcomplex physical domains. Simulating such fluid flowsaccurately and efficiently remains a challenge in theComputational Fluid Dynamics. In doing so, thecomputational mesh must be able to properly representthe physical domain and be organized in an efficientway. This book describes the author s research on thedevelopment of mesh generation and multi-blockalgorithm for 2D numerical models in geometricallycomplex domains. Two improved RL elliptic generationsystems were developed by using the contributionfactors to achieve the mesh density control and theglobal balance of mesh orthogonality and smoothness.A 2D structured mesh generator--the CCHE-MESH hasbeen developed (free athttp://www.ncche.olemiss.edu/software/downloads). Amulti-block algorithm based on a consistentinterpolation method along with a Lagrangianinterpolation method was also developed. It iscapable of maintaining both mass balance and momentumbalance at the block interfaces. The proposed meshgeneration techniques and multi-block algorithm weresuccessfully applied to complex domains and producedsatisfactory results.
