The paper deals with numerical modelling of the high-speed water jet generation inside a diamond orifice of an injection cutting head. CAD model of the diamond orifice received by CT method was used for the creation of a CFD environment. A series of computing operations used for the determination of flow rates and hydraulic powers under different operating conditions were tested. The theoretical studies were experimentally verified by high-pressure flow diagnostics. The main emphasis is placed on the accurate monitoring of the flow rates at given pressure levels. Basic methods and principles used in the experiments are described in the paper. Results of the measurement and comparison with theoretical studies show very good conformity of theoretical and practical tests.
