COMPUTATIONAL INVESTIGATION OF CHARACTERISTICS OF ONE-WAY FORWARD AND BACKWARD ACTION HYDROPERCUSSION SYSTEMS
The mathematical models of positive-displacement hydropercussion systems are presented, their dimensional analysis is performed, the dimensionless variables and the main dynamic similarity criteria are selected. Using alignment charts of output characteristics of the systems plotted in the cross-sections of the spatial similarity criteria, the author analyzes and explains the behavior of the output characteristics and delineates the domains within which the characteristics, given pre-set constraints, are included in the single-stroke limit cycle.
