The Bankoff experiments of condensation in counter-current stratified flow have been simulated by TRAC-PF1/MOD1 and modified TRAC with Bankoff`s own correlations of interfacial friction and interfacial heat transfer coefficient (HTC). Steam flow rate and liquid height have been evaluated. Both TRAC and Bankoff HTCs are strongly dependant on the liquid velocity which is related to the liquid height. The calculations show that Bankoff HTC is much better than the TRAC HTC in the prediction of the stream flow rate and is recommended to replace TRAC HTC in the condensing stratified flow. (author).
