We conduct basic performance analysis and design of turbomachinery using state-of-the-art CFD methods. The entire analysis workflow is fully automated in the Insight CAE framework using only open-source software. This enables very short turnaround times and easy integration into automatic optimization frameworks.
Cavitation is limiting phenomenon for turbomachinery operating in liquids. For prediction of cavitation onset and its impact on machine performance, numerical CFD simulation is the most sophisticated option.
After determination of a propeller open water curve using CFD or any other computational method, further analysis, e.g. propulsion analysis, is required to predict the propulsor performance for a given vessel. We have created analysis software solutions for a seamless integration in the design process, relying solely on open-source software.
Propellers with blades made of fibre composite materials (e.g. CFRP or GFRP) are flexible. The deformation of the blades under operating load must be taken into account during design. We have developed a software solution to perform the necessary CFD simulations with fluid-structure coupling using OpenFOAM and Code_Aster.
