Inclined rectangular weir-flow modeling
WebThis is trapezoidal in shape and is the modification of rectangular weir with slightly higher capacity for same crest strength. The sides are inclined outwards with a slope 1:4 … WebFree-Surface Modeling Flow over a broad-crested weir is a typical air-water two-phase flow. To capture the free surface at the interface between the water and the air, the InterFoam solver in OpenFOAM is used in the present study. This solver is based on the volume-of-fluid (VOF) method developed by Hirt and Nichols [28].

WebfInclined Rectangular Weir- Flow Modeling: Shesha Prakash et al. Jain and Fischer (1982) have studied weirs with crest oblique to the flow axis in the channel. Multi fold skew weirs called Labyrinth weirs were developed and tested by Hay and Taylor (1970). They presented results in the form of curves WebThe flow rate measurement in a rectangular weir is based on the Bernoulli Equation principles and can be expressed as: q = 2/3 cd b (2 g)1/2 h3/2 (1) where. q = flow rate (m3/s) h = elevation head on the weir (m) b = width of the weir (m) g = 9.81 (m/s2) - gravity. cd = discharge constant for the weir - must be determined.
