گروه خدمات فنی مهندسی رهگشافن

NUMECA International’s product strategy is based on the development of automated and customized Flow Integrated Environments (FINE). It allows for rapid design, simulation, and optimization of flow problems. Our software environments cover a wide range of applications while providing feature-specific modules and capabilities dedicated to specific areas of application. Our FINE environments integrate CAD modeling capabilities, advanced pre- and post-processing software, powerful flow solvers, optimization kernels, and a wide range of multiphysics models.

NUMECA’s grid generation software AutoGrid5 and HEXPRESS are unique on the market. They allow the generation of structured and unstructured full hexahedral meshes in a highly automated way, providing a high grid quality within short time frames.

Advanced Rotor/Stator Interaction Techniques

FINETM/Turbo contains features for multiple blade rows and steady or unsteady interaction. Different levels of approximation are available, depending on the nature of the phenomena and the frequency spectrum to be captured.

The non-linear harmonic capability allows significant speed-up for single and multistage unsteady analysis. The table on the right shows figures for a single stage radial turbine, computed on a single processor (3 harmonics have been selected).

FINE/Turbo v7 brings major improvements to the rotor/stator interaction. Multi-row phase-lagged and non-linear harmonic techniques are available.

Fast and Accurate
FINETM/Turbo"s fully hexahedral technology yields accurate and reliable results. Its multigrid engine ensures an extremely fast convergence rate and low memory consumption for large number of grid points. FINETM/Turbo accepts very large aspect ratio cells (up to 5000) and low Reynolds number meshes for an optimal capturing of viscous and turbulent phenomena.

Applications
FINETM/Turbo covers a large range of applications, such as multistage axial, radial, and mixed-flow compressor, turbine, pumps, fans or propellers, and their industrial counterparts such as volutes, diffusers, heat exchangers, and exhaust systems.
