Numerical simulation of supersonic gap flow. [PDF]
Various gaps in the surface of the supersonic aircraft have a significant effect on airflows. In order to predict the effects of attack angle, Mach number and width-to-depth ratio of gap on the local aerodynamic heating environment of supersonic flow ...

Transitional vortices in wide-gap spherical annulus flow [PDF]
We develop a semianalytic formulation suitable for solving the Navier‐Stokes equations governing the induced steady, axially symmetric motion of an incompressible viscous fluid confined in a wide gap between two differentially rotating concentric spheres.

Influences of Gap Flow on Air Resistance Acting on a Large Container Ship
In terms of speed lost and fuel consumed, wind loads are considered one of the main factors for large ship design, especially for container ships. Alongside water resistance, air resistance in strong wind conditions has a significant impact on the fuel ...

Experimental study of controlling tip clearance flow in a pump-jet propulsor
ObjectiveThis paper aims to suppress the adverse effects of tip clearance flow on the hydrodynamic performance and unsteady excitation force of a pump-jet propulsor. MethodAs for the pre-swirl stator pump-jet propulsor, an annular flexible seal structure

A climatology of wintertime low-level jets in Nares Strait
Intense, southward low-level winds are common in Nares Strait, between Ellesmere Island and northern Greenland. The steep topography along Nares Strait leads to channelling effects, resulting in an along-strait flow.

Unstable inner cylinder whirl of concentric double rotating cylinder system
This research investigated unstable inner cylinder whirl in a double rotating cylinder system in which the axis of the inner cylinder is supported elastically in the radial direction and the axis of the outer cylinder is fixed.

Hydrodynamic performance of a rim-driven thruster improved with gap geometry adjustment
The hubless rim-driven thruster (RDT) has become increasingly interesting for ship propulsion. Gap flow has been proven as the main feature of RDT that cannot be simply neglected.

Unstable outer cylinder whirl of concentric double rotating cylinder system
This research investigates unstable outer cylinder whirl in a double rotating cylinder system, with both co- and counter-rotation, in which the axis of the outer cylinder is supported elastically in the radial direction and the axis of the inner cylinder
