COMBINED WAVE-CURRENT FORCES ON HORIZONTAL CYLINDERS

Magnetohydrodynamic Flow in Horizontal Concentric Cylinders

This article presents the exact solutions of the velocity and temperature fields for a steady fully developed magnetohydrodynamic flow of a viscous incompressible and electrically conducting fluid between two horizontal concentric cylinders. Our study focuses on the influence of the Hartmann number, Brinkman number, Péclet number and inner radius on the fluid temperature field, entropy generati...

Simulation of Wave Induced Forces on Semi Submerged Horizontal Cylinders Using OpenFOAM Master of Science Thesis in the Master Degree Programme Naval Architecture

The work presented in this thesis documents the simulation of wave induced forces on semi submerged horizontal cylinders in OpenFOAM, utilizing the blending method for generation and damping of waves. The blending method is not included with OpenFOAM and thus required development before it could be employed. Both a linear Airy wave model and a fifth order stokes wave model are implemented. The ...

Natural convection between two horizontal coaxial cylinders

The objective of our paper is to start the theoretical investigation of the most commonly used mathematical model for natural convection in a horizontal annulus. First, one shows existence of solutions for the unsteady problem. Then, for any Prandtl number and inverse relative gap width, existence and stability of a steady solution is proved, provided that the Rayleigh number is sufficiently sm...

Casimir forces between cylinders at different temperatures

Numerical Investigation on Slot air Jet impingement Heat Transfer between Horizontal Concentric Circular Cylinders

A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...
