• Initialization: compressible flow

  3 September, by J. Gressier
  Initial conditions for compressible flow solver is defined in BLOCK:INIT section. One can use the solution is the CGNS mesh file with TYPE=CGNS or user-defined fields (default) with TYPE=DEFINITION Example (Lamb vortex definition): BLOCK:INIT P = 1.E5 - 1.161*900/2*exp(1-(X*X+Y*Y)/4) TI = 300 VX = 20-30*Y/2*exp(0.5*(1-(X*X+Y*Y)/4)) VY = 30*X/2*exp(0.5*(1-(X*X+Y*Y)/4)) VZ = 0. (...)

  Shock reflection/diffraction over pyramid

  29 August, by J. Gressier
  Case description An unsteady shock wave (travelling Mach = 2.85) impacts a pyramid obstacle. A first reflexion occurs and then the shock is diffracted by the expansion from the spike of this pyramid. The 90 degrees corner trigger a separation. Numerical parameters 600k quad mesh second ordre MUSCL HLLC scheme Results

• Hypersonic flow around two cylinders

  29 August, by J. Gressier
  Case description inviscid flow upstream Mach number 10 Numerical Parameters first order HLLC scheme Results

• Multi-element inviscid flow (Suddhoo-Hall)

  29 August, by J. Gressier
  This inviscid flow on a multi-element airfoil is interesting since this geometry has been defined through a conformal transformation of four cylinders. Thus, a theoretical solution can be computed. partitioned mesh Metis partioned mesh (4 parts)

• Download

  29 August, by J. Gressier
  There are several ways to obtain Typhon sources: some Typhon releases are available as .tar.gz packages on the sourceforge download page you can obtain more releases with some test-cases using subversion: svn export https://typhon.svn.sourceforge.net/svnroot/typhon/tags/rel-n0-n1-n2 /path/to/my_typhon where n0-n1-n2 is the release number (available here) you can use subversion to get an up-to-date (and updatable) development release: svn co (...)
