Investigation of the Hydrodynamic Structure of Throttled Fluid Flow
The objectives of this work are to investigate stream flow in smooth and intensified flow sections and to determine the numerical values of the flow characteristics. The hydrodynamic structure of throttled flow, observed stream flows, vortex and stagnant zones, which depend on the geometric shapes of the flow sections, are presented and described. The numerical values of some flow parameters and optimal geometric dimensions of the throttle channels with different methods of flow throttling are determined. The data obtained will make it possible to develop flow regulators for NPP for high coolant parameters, which ensure stable and reliable operation in startup, normal and emergency regimes of a nuclear reactor.
