Unsteady forces on spherical bubbles

Experiments in Fluids, 1995
An experimental investigation of freely rising spherical bubbles through a quiescent liquid is presented. The objective of the experiments is to examine the validity of a recently proposed history force expression for clean, spherical bubbles at finite Reynolds number (Mei et al. 1994).

The Unsteady Forces Due To Propeller-Appendage Interaction

Journal of Applied Mechanics, 1963
This paper presents a study of the nature of the unsteady forces in the field of a propeller rotating in the vicinity of an appendage. The propeller is assumed to be one of a high aspect ratio while the appendage, although of finite width, is assumed to be infinitely long, and thus the problem is reduced to a study of the unsteady flow field around two

Control of Unsteady Aerodynamic Forces

1990
Abstract : The aerodynamic properties of an airfoil under unsteady conditions are very different from ones in steady conditions because the vortex generated by unsteady separation greatly modifies the loading on the wing. In this study, a fundamental approach was taken to investigate the lift and the velocity field of unsteady airfoils.
