Abstract: The test piece is shown in Fig. 1. The simulation domain is the area of the test piece within red lines, and the area was meshed as shown in Fig. 2. One part where pintle extends into the combustion chamber is complicated and was divided by non-structural grids with axial length of 48 mm. The other part of the combustion chamber, including the nozzle, has a regular structure and was divided by structural grids with axial length of 425 mm. The x coordinate represents axial length, the y coordinate represents height, and the z coordinate represents width. Holes near the observation windows on both sides of combustion chamber are used to inject normal temperature nitrogen to prevent the observation windows from bursting, and to establish the desired combustion chamber pressure quickly.
