Compressible Flow

Analysis of unsteady compressible flow problems invariably involves the resolution of shock waves internal to the computational domain. Generally, these kind of problems typically difficult due to interaction between shock waves, expansion waves, contact discontinuities, as well as well as interaction between waves and wall boundaries. The development of high resolution numerical schemes, TVD schemes (Total Variation Diminishing methodology), has been a significant milestone for approaching the unsteady compressible flow problem.

STORM provides for the calculation of transient flow phenomena where the fluid is considered to be compressible. The Total Variation Diminishing (TVD) methodology has been implemented. The classic shock tube problem is illustrated in the following graph, providing a comparison between the analytical solution and numerical results.
