Software for numerical solution of flow through 2D blade cascades, v 2.0

Original language description

The software, version 2.0, can be used for two different configurations of blade cascade. The periodical case with infinite number of identical profiles is solved in the domain of one pitch. The second configuration is the model of 2D wind tunnel cross section (transonic wind tunnel of IT CAS) with finite cascade of profiles mounted inside test section. Also the 2.0 version of in house software solves the system of Reynolds Averaged Navier-Stokes (RANS) equations and two equation turbulence model on structured multi-block grid. The steady flow is computed by originally implemented higher order implicit finite volume method with AUSM type scheme for convective terms and common central approximation of dissipative terms. The computational code is complemented by post processing tools, which allows evaluation of proper aerodynamics characteristics of computed flow through cascade. Many parameters of mathematical model and numerical algorithm have been tested and results were compared with experimental data in the period 2014 – 2016. The 2.0 software version contains improvements based on the achieved experiences. It increases applicability of software for complicated cases, even though small deficiencies were observed in computed results for some geometries and flow regimes. The software has been tested for transonic flow in wind tunnel test section with mounted tip section type turbine cascade and transonic flow through infinite profile cascade with supersonic inlet flow. The software is the computational kernel (Linux), which performs the numerical simulation. The software is available in a form of paid license. The potential user has to succeed in a several days training course at the workplace of software owner. The contact person: secretary of the Department of Technical Mathematics, Faculty of Mechanical Eng., TU Prague.
