Generic overall isentropic efficiency based on literature review for various compressors

Extends from PolynomialIsentropicEfficiency.

Information

This model contains a calculation procedure for the isentropic efficiency presented by Engelpracht (2017). However, this approach is just fitted to various experimental data obtained by a literature review and, therefore, to use with caution.
