Abstract:Surface tension associated with temperature is usually considered non-negligible to affect discharge capacity of sharp-crested weir when head is low. In the study, a two-dimensional numerical model verified by experiments was applied to simulate the effect of water temperature on discharge capacity of clinging flow for a rectangular sharp-crested weir at low head levels. The results showed that with a same flow rate, differences in the elevation of free surface were minimal between different temperature levels… Show more
