Modeling of intrachamber processes in an oxygen-hydrogen thruster


The result of this work was the creation of the chamber thruster on the perspective oxygen-hydrogen fuel. In the process of designing the used ANSYS CFX system, which was implemented mathematical model of homogeneous multicomponent working body with the mixing and combustion. The calculations were performed on a supercomputer "Tornado" in South Ural State University. The simulation results of the first version of the chamber revealed a non-functional due to the high temperatures in the area of structural elements (external cooling was not provided), and therefore it was decided not to make this chamber. In the process of further computational studies chamber design being modified as long as it was not possible to achieve high combustion efficiency with the presence of structural elements near the zones with temperatures not exceeding the maximum allowed operating temperature of the material. Chamber manufacturer has passed fire tests, which confirmed its performance during long inclusions and showed acceptable power characteristics. It was also a satisfactory agreement between the experimental data with simulation results. Thus, the use of numerical modeling would eliminate the traditional to create new chambers long and costly phase of the comparative tests.
