... Pa (model IA 2 ), and 15–40 Pa (model IA 3 ). Vortex structures provide information pertaining to changes in wall loading due to their spatio-temporal evolution on medial, sagittal, and transverse planes (Fig. 3 ). The extent to which the flow patterns load the wall in terms of WSS and pressure...

... rotational speeds. Vortex structure is captured based on Q-criterion and encloses the cavity in the radial direction, wherein the periphery of the cavity is enclosed by a single tip vortex tube which can explain the generation of drifting stripe-shaped cavity under higher rotational speeds due to tip vortex...

... flow structure, including such phenomena as backflow and vortices, appears upstream of the inducer. In this work, therefore, we conducted 3D unsteady computational fluid dynamics simulations of noncavitating flow in a turbopump inducer, mainly focusing on the vortex structure, for three types of inlet...
