N2 - Computational fluid dynamics models are used to predict the heat transfer distribution on a smooth surface under an array of angled impinging jets. The three-dimensional numerical models simulate impingement with cross flow in one direction. Jet angle is varied between 30°, 60°, and 90° as measured from the smooth flat impingement surface. Conjugate conduction in the heated boundary is included in the analysis. Two turbulence models are examined, the standard k-ε model and the Yang-Shih model. Local and average heat transfer coefficients are compared with test data for 30 test cases. The Yang-Shih model was able to predict average Nusselt number within 2-30%. The standard k-ε model predicts average Nusselt number with 0 to nearly 60% error.
