Fully Implicit, Coupled Procedures in Computational Fluid Dynamics

This book introduces a new generation of superfast algorithms for the treatment of the notoriously difficult velocity-pressure coupling problem in incompressible fluid flow solutions. It provides all the necessary details for the understanding and implementation of the procedures. The derivation and construction of the fully-implicit, block-coupled, incomplete decomposition mechanism are given in a systematic, but easy fashion. Worked-out solutions are included, with comparisons and discussions. A complete program code is included for faster implementation of the algorithm. A brief literature review of the development of the classical solution procedures is included as well.

Serves as new benchmark book for application research Contains all details of construction for implementing the procedures Includes solved problems and applications Includes supplementary material: sn.pub/extras
