ABSTRACT
A solution adaptive local mesh refinement method has been developed within a structured grid system for mixed convective heat transfer to fluids at supercritical pressure which has very significant localised distortions due to strong variation of properties. The adaptive mesh refinement method developed was able to achieve a solution accuracy better than one achieved using a very fine fixed-mesh grid but with only a small fraction of the CPU time. This paper describes the key strategies employed in the method developed. Simulations of experiments are presented and discussed.
