Abstract
Jet impinging onto a hole having different configurations of barreling is simulated in relation to the laser produced hole. The flow and temperature fields in the hole are predicted for different hole barreling configurations. The Nusselt number and the skin friction variations along the hole wall are determined. The hole wall is kept at 1500 K to resemble the laser drilled hole. Air is used for working fluid, while Reynolds' stress model is incorporated to account for the turbulence. It is found that the different configurations of hole barreling significantly influence the Nusselt number and the skin friction in the hole.
