Book Description
A low-speed experimental investigation was made of the filling effect observed when a screen or similar resistance is placed across a diffuser. Results are given for three diffusers of circular cross section with a variety of screen arrangements. The filling effect was observed to be real in that screens could prevent separation or restore separated flow in diffusers even of extreme divergence and to depend on screen location and pressure-drop coefficient. The effects of single and multiple screens are shown and the mechanics of the filling effect and possible efficiencies are discussed, as well as applications to damping screens as used in wind tunnels to reduce turbulence.

Book Description
This book is intended to be a valuable addition to students, engineers, scientists, industrialists, consultants and others providing greater insight into wind tunnel designs and their enormous research potential. It is a compilation of works from world experts on subsonic and supersonic wind tunnel designs, applicable to a diverse range of disciplines. The book is organised in two sections. The first section comprises of three chapters on various aspects of stationary and portable subsonic wind tunnel designs, followed by one chapter on supersonic wind tunnel and the final chapter discusses a method to address unsteadiness effects of fan blade rotation. The second section contains four chapters regarding wind tunnel applications across a multitude of engineering fields including civil, mechanical, chemical and environmental engineering.
