Numerical calculation of developing laminar flow in rotating ducts with a 180° bend

F. Papa, K T.G., K.J. DeWitt, K. Vaidyanathan

This study is concerned with developing laminar flow of an incompressible, Newtonian fluid, having constant viscosity, rotating in circular and rectangular ducts that contain a…

Effect of viscosity ratio, spin and Reynolds number on the flow characteristics about a liquid sphere in a gas stream

M.A. Antar, M.A.I. El‐Shaarawi

Boundary‐layer flow around a spinning liquid sphere moving steadily in a gas stream is investigated numerically. The shear stress exerted on the sphere's surface results in…

Jet impingement onto a cavity

B.S. Yilbas, S.Z. Shuja, M.O. Budair

Jet impingement onto surface finds wide application in industry. In laser processing an assisting gas jet is introduced either to shield the surface from oxidation reactions or…

Laminar‐turbulent transition for low Reynolds number mixed convection in a uniformly heated vertical tube

A. Behzadmehr, N. Galanis, A. Laneville

Upward mixed convection flow of air in a uniformly heated vertical tube was studied numerically using the three‐dimensional elliptic conservation equations and the Launder and…

Effect of aspect ratio and eccentricity on heat transfer from a cylinder in a cavity

Syeda Humaira Tasnim, Shohel Mahmud, Prodip Kumar Das

This paper presents the hydrodynamic and thermal behavior of fluid that surrounds an isothermal circular cylinder in a square cavity. Simulations were carried out for four aspect…

Investigation into a confined laminar swirling jet and entropy production

S.Z. Shuja, B.S. Yilbas, M.O. Budair

A confined laminar swirling jet is an interesting research topic due to flow and temperature fields generated in and across the jet. In the present study, a confined laminar…
