Radial Compressor Test Data Processing with Real Gas Equation of State

Popis výsledku v původním jazyce

In the paper, a calculation of radial compressor characteristics from measured data is dealt with. The measured quantities as temperatures, pressures, working gas relative humidity, shaft rotational speed and torque are processed to obtain absolute and dimensionless parameters of the given machine. The methodology is generalized to both experimental and production machines and it deals with incorporation of any suitable equation of state. A modular and configurable in-house code is used for this purpose. It adopts the ASME performance test code for compressors scheme of measuring stations, stages, sections and machines. The theoretical background and the structure of the program are described. Benedict-Webb-Rubin equation of state for real gases is implemented. Gas humidity, orifice flowmeter, bearings mechanical losses and torquemeter measurements are covered. Various cases of measuring station calculations considering high speed and/or rotational flow based on total and static state parameters are elaborated. Polytrophic compression and the accuracy of evaluation of polytrophic efficiency are discussed in terms of various real gas corrections. Conversion of the results to comparable form is explained
