Abstract

The influence of conical and annular nozzle geometric configurations on the flow structure and heat transfer characteristics near the stagnation point of a flat plate with limited heated area was analyzed. The conical and annular conical nozzles were designed such that the exit area of both nozzles is the same and the mass flow rate passing through the nozzles is kept constant for both nozzles. It was found that nozzle exiting velocity profiles differ considerably with changing the nozzle cone angle. The results can be used in laser machining applications to improve the end product quality.
