【Abstract】 The behaviour of oil-film and paint dispensation are studied in this paper on purpose of using oil-film method. Two paint dispensations for use with flowvisualization in hydraulic machine are given. And oil-film graphs of flow manner in extremity clearance of water turbine’s guide vane and the flow movemental track of centrifugal pump impeller are obtained by using this kinds of paint dispensation.更多还原
