University of Tehran Press Journal of the Earth and Space Physics 2538-371X 27 1 2001 03 21 - - 13319 FA Journal Article 1970 01 01 In this study, turbulent flow around a Guassian hill in a water tunnel is studied. Using a hot film anemometer, velocity and turbulent qualities (such as turbulence flux and intensity) is measured at different parts of the model. To understand these measurements, mean velocity deviation and perturbation velocity fluctuation contours, also turbulence flux and intensity profiles are presented and the results are consistent with those obtained by other investigators. Also the cavities in the downwind of the hill cause intense turbulence its scale being in order of cavities. The increase of velocity around the hill especially above the crest is significant. These studies in the use of optimum wind energy in hilly regions are useful. In this study, turbulent flow around a Guassian hill in a water tunnel is studied.
