We present the results of a comparative study on thermally stratified
tanks for hot storage. A two-dimensional model is employed. A numerica
l solution was obtained using the control-volume technique due to Pata
nkar. The two-dimensional model was simplified for the pure conduction
case. Results from the two models were compared with each other and w
ith available numerical and experimental results. (C) 1997 Elsevier Sc
