Master thesis - CFD simulation of a heat pump centrifugal compressor

High-temperature heat pump is an excellent solution for the district heating when the used electricity is green and there is a growing market in that area. Essentially, low global warming potential refrigerants (for example R1234ze(E) and R1234ze(Z)) are anticipated to be the refrigerants of choice for high temperature heat pump systems in industrial applications.

The project explores the implementation of refrigerant/s in numerical tool, the flow simulation and evaluation of the centrifugal compressor in CFD, and development of the process. Two different commercial CFD tools will be explored and compared, and an automatic/semi-automatic process should be developed from pre to post-processing starting from the blade geometry.

In the project the main goal is to perform CFD simulations of a centrifugal compressor which can handle a pressure ratio of 12 to 17. The compressor should be 2 stages centrifugal compressors. R1234ze(E) refrigerant should be taken as a reference refrigerant for the comparison.

Two master thesis students are expected to perform the thesis. The student should use two different CFD tools and compare the results and develop the process for the two CFD tools.
