Abstract: PAT(pumps as turbines)is one of the best alternatives for energy recovery. PAT is very important for waste energy resources recovery in industry and the micro-hydropower development in remote areas. In order to further investigation on PAT, the main texts on PAT were briefly reviewed. The available reference materials of research on pumps worked as turbines were mainly conducted based on experimental, theoretical and numerical ways. The relevant research fields of PAT were summarized, such as the optimization design of flow passage components in PAT and performance improvement, the operational stability of PAT, PAT′s type-selection and performance prediction, especially the prediction for BEP(best efficiency point). Performance parameters of the pumps and PAT were obtained through experiments. The relationship of performance parameters between pumps and PAT was predicted by theoretical analysis and the empirical formulas based on the experimental data. The PAT performance can be determined by comparing the results from CFD prediction and the tests. Finally, the prospect and future tendency of research on PAT was proposed, in which the accurate method of PAT type selection, the new design theory, vibration and off-design operational stability as well as the high-power and multistage PAT study were included.
