Turbine, Pump & Compressor (Axial or Centrifugal): Multidisciplinary Turbomachinery Design, Analysis & Optimization

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Starting from the preliminary design, our engineers progresses through a 1D inverse task solver optimizer, to continue with meanline (1D) and axisymmetric (2D) analysis, profiling and 3D blade design, 3D finite element analysis (FEA) for structural calculations, secondary air flow hydraulic and thermal calculations (including cooling), rotor design, bearing analysis, rotor dynamics and 3D CFD calculations. We can design axial turbines, Axial Pump, Centrifugal Compressor, Centrifugal Pump and Mixed Flow Compressor/Turbine with or without any pre-loaded profiles, with prismatic (cylindrical) or twisted blades, multiple extractions/injections, inter-stage heat exchangers, Curtis & Rateau stages, impulse & reaction designs, drilled and reamed nozzles, partial admission, etc.
