Abstract
Control engineering studies during the design of an industrial process frequently use simulation methods which require its operation to be represented in mathematical terms. This contribution reviews the salient features of various types of pumps and compressors encountered in such processes and presents models which embody these properties in a form suitable for use on a computer.
In general, these represent a compromise between the extremes of simplicity and rigour which has proved satisfactory in this context. Each application should, however, be the subject of engineering judgment on the degree of approximation which will be consistent with the quality of the data available and the objectives for which the simulation is being performed.
