EXPERIMENTAL BENCHMARKS FOR COUPLED CONVECTION AND HEAT TRANSFER
IN SOLID-LIQUID PHASE CHANGE

PAGE COMMING SOON, NOT FINISHED!

We propose three experimental benchmark problems to validate physics of the numerical algorithms designed for the computation of coupled coupled natural convection/phase change problems.

A comparison exercise for numerical codes simulating solidification in the presence of natural convection of a pure substance of well known properties (water). Consider a differentially heated cube shaped cavity filled with water.

horizontal gradient cavity
After a natural convection established, cold wall temperature is set to -10C. Four non-isothermal walls are made of Plexiglas. Freezing process starts from well defined state ("warm start"). Benchmark for the starting solution is given here.

People working in this field are warmly encouraged to participate to this benchmark exercise. A synthesis and comparison of the results will be presented at PCC05 Workshop.

Potential contributors to test their codes should contact T. A. Kowalewski and B. Sarler.
