Structural design and application analysis of Laval nozzle

The purpose of this project is to apply the principle of Laval nozzle to reconstruct the gas stove, improve the combustion efficiency of the gas stove, transform its tail gas products, and reduce the tail gas pollution of the gas stove. In this paper, ANSYS software is used to simulate the Laval nozzle of micro modular liquefied gas micro propulsion system, and the relationship between the size factors of the nozzle and the flow effect of liquefied gas is obtained.
