introduction
The utilisation of Computational Fluid Dynamics (CFD) within turbomachinery companies has experienced significant growth. This has notably facilitated the design and optimization of modern turbines, pumps, and compressors, resulting in enhanced aerodynamic characteristics and increased efficiency. With improved accuracy, CFD enables the precise prediction of flow and acoustic characteristics of turbomachines even during the initial design phase. Additionally, CFD’s adoption leads to shorter design cycles, improved performance, cost-effectiveness, and reduced weight. Furthermore, CFD plays a crucial role in various applications such as noise reduction, pressure loss mitigation, prevention of cavitation, better blade designs, and accurate heat transfer modelling.

Optimization of a Radial Compressor
Using CFD models, pressure, velocity, and temperature fields are visualized at a particular operating point for the new design.
CFD analysis was done to validate the centrifugal compressor, predict the efficiency of the turbo compressor, study the flow behavior through the compressor, and predict the efficiency of the given design. The total isentropic efficiency was calculated and compared with the test rig result.

Computational Fluid Dynamics (CFD) would be a useful low-cost optimization tool for flows through a radial turbine. Using CFD models, pressure, velocity, and temperature fields are visualized at a particular operating point for the new radial turbine operating at different opening positions.
CFD and Heat Transfer analysis were performed on a radial turbine with a cartridge mechanism for the maximum and minimum opening positions. The obtained solutions were compared with the tested results for validation purposes. The total static isentropic efficiency was calculated and compared with the test rig.
Benefits
