Abstract
A numerical study of high-temperature nozzle flows at low Reynolds numbers is performed using the DSMC method. The modeling issues important for an accurate prediction of the micronozzle performance such as the gas surface interaction and thermal relaxation are considered. Results of the DSMC modeling for a heated nitrogen nozzle flow are compared with experimental measurements of nozzle efficiency at Reynolds number from 200 to 400. Hydrogen-air combustion products expanding through a micronozzle for the Reynolds number ranging from 200 to 2,000 is considered. It is found that modeling of internal energy relaxation is important in such flows.
