Horizontal Forces Due to Waves Acting on Large Vertical Cylinders in Deep Water

Drag forces on vegetation due to waves and currents

The research focused on the variation trend of drag coefficient with Keulegan-Carpenter number in vegetation mimics in pure wave and combined current-wave flow conditions. Experiments were carried out in the Environmental Fluid Mechanics Laboratory at Delft university of Technology. Completion of this thesis was only made possible with the help of many people who graciously shared their time, e...

Natural Convection Heat Transfer From Horizontal Cylinders in a Vertical Arra Confined Between Parallel Walls

Laminar natural convection from an array of horizontal isothermal cylinders confined between two vertical walls, at low Rayleigh numbers, is investigated by theoretical and numerical methods. The height of the walls is kept constant, however, number of the cylinders and their spacing, the distance between the walls and Rayleigh number have been varied. The optimal spacing (confining walls) and ...

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...

Shear Localization due to Strain Softening in Side Pressed Cylinders

In this paper, shear localization due to strain softening in sidepressed cylinders, is inverstigated. Shear localization causes formation of macroscopic shear bands which can be obsserved in the metallographic cross-section. In this paper, for the first time a method is presented in which a simple two-slice model is used to study the formation of shear bands. The results obtained form this mode...
