| Abstract: | In order to explore the factors affecting the size fluctuation for the variable-burning rate propellant in the co-extension process,numerical simulation method was used to simulate the flow under different operating conditions.Results show that the screw velocity fluctuation has more influence than the entrance pressure fluctuation on the size fluctuation of the variable-burning rate propellant,especially have an influence on the interface radius.The entrance pressure fluctuations have an impact on the size... |
