The Wall Function for large eddy simulation (LES) proposed by Cabot is extended to the turbulence closure models. Predicted results are discussed and compared with well-documented experimental results. Although complete agreement with experiment is not yet achieved for some cases, it shows that the model with Cabot’s Wall Function significantly reduces the computing resources (CPU & storage) required where the first off-wall velocity nodes are located at 60 < y+ < 180; and in most cases improves predicted results.
