Abstract

The present lecture deals with issues related mainly to the geometric and algorithmic complexities, i.e. how to handle irregular shaped arbitrary geometry and how a generalized pressure-based algorithm is developed which can, in principle, compute flows at all speeds ranging from incompressible to hypersonic. The pressure-based method is emphasized since it is not covered in details in most of the currently available textbooks and the methodology has reached a certain maturity during the last three decades so that it can adequately handle many issues encountered in flow problems of engineering interest. Section 2 discusses the different possibilities and provides some strategies for the development of general, accurate and efficient pressure-based finite volume algorithms for prediction of flow in complex configurations. Section 3 provides the detailed formulation of a particular pressure-based algorithm developed by the author and his colleagues at the University Karlsruhe, Germany and NAL, Bangalore. Some interesting application examples of incompressible and compressible flow are illustrated in Section 4 to demonstrate the universality and capability of the algorithm whereas, Section 5 presents a few concluding remarks.
