Abstract
A revised form of the low-Reynolds-number κ—ε turbulence model is presented that aptly describes recirculating (separated and reattached) flows. The revised model is well suited for low to moderate Reynolds numbers. It is applied to two-dimensional channel flows, flow over a backward facing step, and flow over a forward facing step to calculate flow fields and surface heat or mass transfer rates. Results from the present model are in better agreement with experimental data than other low-Reynoldsnumber models. Asymmetric flow through an array of rectangular cylinders, as well as in a two-dimensional symmetric sudden expansion duct, is found numerically and supported by experimental results.
