In order to assess accurately the standard k-ε model in a three-dimensional recirculating flow, a series of numerical calculations of a jet in a crossflow have been made employing progressively fine finite-difference meshes consisting of up to 2.4 million grid nodes. The discretized equations have been solved with a blockimplicit multigrid algorithm that is observed to converge efficiently. The calculated velocity and turbulence fields are compared with experimental data. It is observed that the general features of the flow are well predicted, but there are appreciable discrepancies between measured and calculated values. Even with current fine resolution, the calculation cannot be said to be completely grid independent; however, the major disagreements are believed to result from the turbulence model.
