Modeling Compressor Pressure Ratio vs. Mass Flow Rate Including Choke Line and Surge Line Using Scaling Theorem
In this paper, a procedure to obtain the compressor map (pressure ratio vs. mass flow rate) is showed by scaling of the available compressor maps with similar shape and design using scaling theorem. The reason to develop such procedure is that in industrial application, a new compressor map need be developed before the complete geometry and hardware of compressor are known. Such procedure is especially useful for users such as engine or vehicle OEM to quickly select turbocharger compressor independently. The scaling law is used to model the non-dimensional parameters of compressor head coefficient vs. mass flow coefficient. Detail procedure from the non-dimensional parameters to the final compressor performance data are described.
