Abstract
Jet impingement onto a kerf is considered in relation to laser cutting process. Flow and temperature fields are predicted using the three-dimensional modeling. In the simulations influence of kerf wall wedge angle on the Nusselt number and the skin friction at the surface of the kerf wall is examined. The RNG k-ε model is incorporated to account for the turbulence. A control volume approach is introduced to discretize the governing flow equations. It is found that the kerf wall wedge angle has considerable influence on the Nusselt number and the skin friction.
