Summary

An experimental and analytical study of screw compressor operation under unsteady conditions has been carried. For this purpose a one dimensional model of the processes within a screw compressor based on the differential equations of conservation of mass and energy was extended to include other plant components, taking into account tanks and connecting piping. The analytical model was then further developed to demonstrate whole plant transient operation when a screw compressor is connected with other elements in a complete air compressor system, consisting of a positive displacement compressor, low and high pressure tanks and connections between them, and auxiliary equipment, such as control valves, storage tanks and oil and air coolers. Results of the model have been compared with experimental data and show good agreement. The model allows simulation of unsteady plant operation under various scenarios which may occur within engineering practice and calculates plant dynamics at any given time.
