The Axial Flow around a Stepped Cylinder with Small Attack Angle

Numerical Investigation of Turbulent Flow around a Rotating Stepped Cylinder for Corrosion Study

The Canadian Journal of Chemical Engineering, Volume 81, February 2003 Complex flows with boundary layer separation and reattachment commonly occur in situations of practical interest. In such flows, any accompanying heat or mass transfer is strongly influenced by the fluid dynamics. For example, rates of heat or mass transfer to the wall can have large variations in the reattachment region. In...

Flow around a rotating, semi-infinite cylinder in an axial stream.

This paper concerns steady, high-Reynolds-number flow around a semi-infinite, rotating cylinder placed in an axial stream and uses boundary-layer type of equations which apply even when the boundary-layer thickness is comparable to the cylinder radius, as indeed it is at large enough downstream distances. At large rotation rates, it is found that a wall jet appears over a certain range of downs...

AXIAL FLOW OF CASSON PLASTIC MODEL IN ANNULUS WITH A ROTATING INNER CYLINDER

Supersonic Unsteady Flow around a Capsule-shaped Abort System with Angle of Attack

Supersonic flow over a capsule-shaped abort system with angle of attack (AoA) of α, which is boosted by supersonic aerodynamic interference, is investigated numerically through the 3D simulation. The objective of this study is to examine the effects of AoA on aerodynamic stability. In the previous study, the flowfield around this system at α = 0 is unsteady and has a strong periodic flow oscill...

Numerical Study of Turbulent Flow around a Generic Airship at High Angle of Attack

This article presents a numerical study of turbulent flow around a generic three-dimensional prolate spheroid with a 20◦ angle of attack. The Reynolds number we use is a moderate one Re = 4 × 104. In this work we compare three different turbulence models : the RANS k − ε, the LES Smagorinsky and the VMS-LES. The numerical code makes use of a mixed FE/FV formulation based on tetrahedra. A Roe’s ...
