| Abstract |
In laboratory experiments it is not possible to simulate all of the phenomena which affect the flow within a valley. It is especially difficult to simulate Coriolis effects which may be important for large valleys and thermal effects associated with diurnal heating and cooling. However, many aspects of this problem can be studied using nonrotating, isothermal flow over geometrically simple models. This paper summarizes a series of such experiments on the flow over a cosine-shaped ridge and within a valley formed by a pair of such ridges when there is a stable ambient flow normal to the axis of the ridge. Three experimental parameters were varied during the study: the steepness of the ridges, the separation distance between the ridges and the Froude number. (ERA citation 12:009887) |
