| Abstract: | Multiphase detonation process of suspended gasoline/nano-aluminum-powder liquid drops and air mixture in a circular tube is numerically simulated in this paper.The multi-fluid model with chemical reaction is used to treat the liquid,aluminum and the oxidizer under one dimension Euler coordinates.The conservation element and solution element(CE/SE) based on rectangular mesh method is applied to solving the controlled equations in which the source items are dealt with fourth-order Runge-Kutta method.The influ... |
