jet vanes gas-solid two-phase flows solid particles temperature contours pressure contours
According to thrust vector control motor states,a RNG k-ε turbulence model with large Reynolds number and Euler-Lagrange two-phase model are adopted to study the gas-solid two-phase flow around jet vane.The temperature and pressure contours on jet vane surface are numerically simulated and presented.The curves of lift force and resistance force vs rotation angles are given.Compared with the pure gas phase,when jet vane rotation angles are less than 25°,the lift forces increase and the resistance forces are unchanged for the gas-solid two-phase flow.When rotation angles are larger than 25°,the lift forces and resistance forces decrease.The results show that the solid particles has little influence on pressure distribution on jet vane,but has great influence on the temperature distribution in two-phase flow,so that the temperature of the whole jet vane rises in two-phase flow.
