Other AbstractThe QDS (Quiet Direct Simulation) method for Euler fluid is introduced. As the most important part,the current method extends the previous Euler solver developed by Albright and M.R.Smith mainly by three aspects: (1) The gradients (density,temperature,velocity) are calculated when updating the grid properties of mass,momentum and energy from the individual particle at the third step in the QDS method, hence a fully improved second order scheme. (2) A kind of new process for updating the grid properties from the individual particle is developed,which cut down the times for the most part to seek the total particles,thus improving the computing efficiency signally. (3) Several slope limiters are employed in the second scheme and their performances are tested.
