Pressure based finite volume method for calculation of compressible viscous gas flows

 

Pressure based finite volume method for calculation of compressible viscous gas flows

The algorithm SIMPLE-TS (Time Step) is published in [1]

The accepted manuscript can be downloaded from here, the paper in it`s final mode is avalible here.


The source code ver. 1.1 of the algorithm SIMPLE-TS written in C++ and the short help (release date: August, 2011).
Notes:
- The parallel organization is according [4].
- The parallel efficiency is improved according v1.0 (see [4]).
- The bugs of the code, when are used more then 20 CPU are solved.

Problems:

Pressure driven gas flow in s microchannel - the problem is defined in [1]

Unsteady pressure driven gas flow in a microchannel - the problem is defined in [1]

Flow past a confined squaree in microchannel - Mach number 0.1 - the problem is defined in [1] (file 1 anf file 2)

Flow past a confined squaree in microchannel - Mach number 2.43, space step 0.05 - the problem is defined in [1]

-----------------------------------------------

Increasing velocity at the channel inflow from Mach number 2.43 to Mach number 4.86, for Knudsen number 0.05.
