Numerical Study of Slot Jet Impingement on a Cylinder by Using Two-Equation Turbulence Models

In this paper, the numerical results of turbulence slot jet on a heated cylinder are presented. The main objective of this study is to recognize suitable RANs turbulence model, which predicts the accurate results as compared to the previous published experimental results. To model turbulent flow, widely used k–e Std., k–e realizable, k–e RNG, k–ω Std. and k–ω SST turbulence models were used. It was found that Std. k–ω turbulence models better predict as compared to other turbulence model in the pressure distribution on the cylinder. However, the k–e Std. and k–e RNG models better predict the heat transfer as compared to other turbulence models.
