Abstract
In tbis research
the eff ect of wi.nd on the Outer
!’
surfac.es of bigh cooling towers was studied and its stability
under too variation of wind ve Loci,ty~
Tl~ tests ,:!,ere carried out using an open jet wind tunnel
which v:as de ai.gned for this purpose at the Flmd Mechanics
Labor-at.o ry t Faculty of Engi.i.’leerip-{S,Ain Shams Univers.ity~
Four Sffiall scale cooling tower models, which are largely
used in thermr?’.:_power stations and industrial plants, were
designed. ::
1- To obtain the pre ssure distribution at different sections
for each tower at different wind ve Loci,tie s and at different
gap widt:2s 0
2- To co·::;ain the ve Loci.tiy profile s round the cooling tiower s ,
3- Flew visuaJj_zation around t~ coo Li.ng tower body using the
tuft te chn.i.que:;
The ::>·2sults of this research were:
a) .An expression f’o.r the velocity profile s around the cooling
tower was deduced b) An expression which correlate 3 the flow separation point
along the tower surface and its hyperbolic formula!
e) The rate of change of momentumflux distribution along the
the tower surface was plotted~
It was finally concluded that the gap width has no effect
on the flow cu t sd.de the cooling tower, although 1t affects the
flow inside the tower.
