Usage instructions

How it works

First, a database of 3708 radial compressors is generated using the TURBIGEN design code. For mean-line designs sampled from the full eight-dimensional design space, geometry is created and a Reynolds-averaged Navier--Stokes solution obtained. Then, polynomial surface regression is used to create a continous function mapping efficiency as a function of the design variables. By quantifying the influence of different loss sources, the physical mechanisms that cause drops in efficiency at the boundaries of the design space can be deduced. See the paper for more details:
