Dealing with Irregular Flow Domains and Complex Physical Phenomena

Abstract

The methodology discussed in Chaps. 2–5 is applicable for simple cases of fluid flow. Practical flow problems are often more complicated and require additional measures to get to a solution. If one leaves aside the very difficult and case-specific question of the problem formulation itself (e.g. what flow to simulate, what data is available, why one would want to use CFD as opposed to other modelling approaches, what exactly one would like to get from less then the problems associated with practical flow situations can be divided, especially from CFD solution point of view, into two categories: those associated with irregular and complicated flow domain, and those associated with complicated physics. In the former, the simplistic approach to grid generation adopted in earlier chapters is not applicable.
