Abstract

Numerical simulation of flow field and thermal transport processes for a turbulent jet impinging on the surface of a cylindrical object, e.g., hot dog, were carried out at different jet velocities. Numerical predictions for average surface heat transfer coefficient were compared with the experimental results obtained using a lumped mass approach for model aluminum cylinders. Results indicated good agreement between the numerical and experimental results over the range of jet velocities, i.e., 10-40 m/s. Further experiments were carried out with real beef hotdogs to obtain center point temperature-time history during hot air impingement baking process. The experimental data agreed well with the numerical predictions when the impinging jet temperature was below 100C.
