To study the influence of the exhaust plume on the launching equipment and the environment, the plume of the rocket launching process was researched. The dynamic updating method was used to simulate the launching process of the rocket. The finite volume method was used to calculate the ablation and impact of the plume on the launching equipment. The results show that the flame deflector and first...
To decrease the influence of the staircase effect to the shape and dimension precision of rapid prototyping part, a method of blending the adjacent section-contours in CAD model using rotary rays is explored in this paper. The current and the next section in CAD model were projected onto a horizontal plane, and the outer and the inner boundary were obtained by computing the sections' union and intersection,...
One of the most important characteristic signatures of the exhaust plume from rocket motor is the afterburning phenomenon, and the injected water into the plume could inhibit the afterburning. The calculation model for the gas-liquid multiphase flow field with chemical reaction in the plume is built. By inducing the energy source terms caused by the vaporization of liquid water, condensation of the...
