ABERTHAW 'B' POWER STATION MODEL STUDY OF A BEND AND DIFFUSER COMBINATION IN THE COOLING WATER INTAKE TUNNELS

摘要

Flow through a combination of a bend of variable cross-section followed by a diffuser was studied with the aid of an air model (model scale 1:19.2). The effects of fixing vortex generators in the bend and of allowing for access to the bend by means of an access pit in the outside surface of the bend were investigated.nThe results obtained are compared with some previous work on bends and diffusers and predictions are made of the expected head losses in the prototype structure.
