Hi Rahul,
Following on from J.C. Kim's message, please refer to Reference [1] in our paper* - relating to work by Professor John Hunt - for the seminal work on calculating CET. This depends largely on the solidification velocity (V) and the thermal gradient in the liquid (G). I think J.C. Kim uses R to signify this velocity - or rate.
Once you can calculate G and V you can apply the Hunt criterion for CET. How you calculate or estimate G and V is up to you - but you may need to use computational methods, as inferred by J.C. Kim. Our paper* provides a review of the current state of the art.
