Abstract: A general analysis of the resistance to rotation of disks at high Reynolds numbers is presented. The theoretical calculations of the fluid-induced torque on free and enclosed, smooth and rough ...

Abstract: A simple turbulent energy model, based on an improved version of Wolfshtein’s model for Newtonian flows, with a variable damping parameter, is used to describe the effect of linear polymers ...

Abstract: Rectangular prismatic bodies can assume either a translatory or an auto-rotating mode of motion during free motion in the atmosphere. The translatory mode is stable only when the dimensionless ...

Abstract: In this paper measurements are presented of mean velocities, turbulence intensities, Reynolds’ stresses, and the wall friction in a radial wall jet formed by an impinging circular jet on a ...
