Considering the complexity flow characteristics and rotation curvature effect on internal unsteady in a centrifugal pump, hybrid Reynolds-averaged Navier–Stokes/large eddy simulations method based von Kármán scale correction of has been established, its effectiveness also verified. Proper orthogonal decomposition is used to study structure pump for advantages turbulence analysis. Further, complex vertical single-stage marine pumps have studied, relationship between energy distribution...
Cavitation-induced vortex and energy loss are critical topics in the field of hydraulic machinery. Through a combination experimental numerical analysis, this paper investigates how blade loading affects vortical structures during cavitation waterjet pump. The flow rate conditions changed tip pressure loading, which significantly affected trajectories primary leakage secondary cavitation. A considerable gradient at attached cavity closure region leads to wall reentrant jet side-entrant jet,...
The gas–liquid separator is a key component in the gas removal system thorium molten salt reactor (TMSR). In this paper, an experimental study focusing on core formation was carried out. We observed that of air depends primarily back pressure separator. Gas visualized for range pressures, swirl numbers, and Reynolds numbers. Analysis flow patterns indicated may be defined as four stages: “air with suction,” “tadpole-shaped core,” “cloudy “rod core.” When rod achieved, bubbles will separated...
<div class="section abstract"><div class="htmlview paragraph">In driving condition, the electric drive system of vehicles generates significant heat, which increases temperature motor, leading to reduced performance and energy loss. To manage motor recover energy, a plate-fin heat exchanger (PFHE) is used facilitate exchange between vehicle's thermal management system. In this study, Computational Fluid Dynamics (CFD) method was investigate fin structure on flow within PFHE. The...
The creation and control of homogeneous isotropic turbulence in laboratory settings is practical significance. In this paper, we propose a novel design for generation apparatus driven by two pairs oscillating grids, with the object striking balance between stochastics momentum injection flexibility turbulent kinematic energy (TKE). To validate performance system, tomographic particle image velocimetry measurements are conducted. Based on Reynolds decomposition, characterize secondary flow...
Non-uniform inflow at the inlet of a reactor coolant pump generates performance variations, such as in head, efficiency, cavitation, and vibrations. The three-dimensional velocity pressure for non-uniform are reconstructed via time-resolved tomographic particle image velocimetry to evaluate its effect on pump. Five volume fields were through multiplicative algebraic reconstruction technique, which constitutes entire flow field. statistics used study characteristics. contains two large-scale...
A reactor coolant pump (RCP) is essential for transporting in the primary loop of pressurized water reactors. In advanced passive reactor, absence a long pipeline between steam generator and RCP serves as transition section, resulting non-uniform flow field at inlet. Therefore, characteristics should be investigated under to determine its influence on pump. this study, pressure pulsation were examined time frequency domains, sources low-frequency high-amplitude signals analyzed using wavelet...
Venturi tube is based on turbulent flow, whereby the microbubbles can be generated by fragmentation. This phenomenon common in several venturi bubblers used nuclear, aerospace and chemical industries.
