Investigation of Complex Characteristics of Waterjet Propulsion Device with Intake Grid
Published 2021-01-01“…The causes of hydraulic loss in the contraction segment and straight pipe segment are the intake grid and the inflow velocity, respectively; meanwhile, the loss in the belt pipe segment owes to the vortex, flow separation, and impact on the back. The intake grid has a positive effect on the depth of the inlet velocity profile, but a negative effect on the width of it. …”

Influences of Dual Air-Swirler Angles on Swirling Injection and Combustion of Kerosene-Air at a Supercritical Pressure
Published 2025-01-01“…Numerical results indicate that the inner air swirler exerts strong impact on fuel-air mixing and chemical reactions inside the inner injector, leading to a Y shaped recirculating flow and a V shaped flame at an inner swirler angle of 40°. The precessing vortex core (PVC) is generated by the inner air swirling injection, and detailed analyses reveal that the PVC frequency is controlled mainly by the inner swirl number and the maximum axial velocity from the inner injector. …”
