Physical and mathematical fundamentals of cavitation
Original language description
Increasing of operating parameters when using fittings in hydraulic circuit puts high demands on their durability and reliability. Under these operating conditions, the valves are mechanically worn mainly by cavitation. Therefore, it is necessary to identify the conditions of normal operation and operation with cavitation. One way of cavitation determining in addition to the practical test is mathematical modeling. Firstly, it is necessary to specify the mathematical models and verify their correctness by verification with experiment. The detailed analysis of the results obtained in a laboratory apparatus of the water flow through the convergent-divergent nozzle of rectangular cross section and the results of modeling, it was found that the cavitation is a term containing vapour and air cavitation, while both physical processes occur simultaneously. Experience has been applied to a practical problem of water flow through control valve. (C) 2016 Author(s).
