A criterion to determine throat diameter of a supersonic nozzle is determined from conservation equations of flow of gases and applied successfully to nozzles used in impinging jet steelmaking processes. Influence of surroundings on the nozzle design is evaluated in terms of the force coefficient. It is suggested that a supersonic nozzle design delivering gas at exit pressures slightly greater than the surrounding pressure or overdriving a correctly designed nozzle is beneficial under the conditions of impinging jet steelmaking practice.
