SUMMARY We present a method that simultaneously solves the pressure‐correction equation and the energy equation in a conventional SIMPLE scheme. In comparison to other techniques, the new method leads to a remarkable reduction in the number of required iterations, in particular for problems characterized by significant temperature gradients. It is shown that this translates to very attractive computing times. Copyright © 2011 John Wiley & Sons, Ltd.
