Multifarious hydrodynamic cavitating flow patterns have been detected in the flow of de-ionized water through a 40.5 μ m wide and 100.8 μ m deep rectangular slot micro-orifice established inside a 202.6 μ m wide and 20 000 μ m long microchannel. Introduction The flow of fluid through a vertical slot is considered. This consists of a flow from a horizontal uniform channel of finite depth into a vertical slot under the influence of gravity. The implications of treating flow through a side slot as through a small orifice, as reported in the literature, are also studied. For different combinations of slot openings and sill heights, data for a set of 110 runs have been obtained.
Orifice Discharge into Free Air
An orifice is an opening with a closed perimeter through which water flows. Orifices may have any shape, although they are usually round, square, or rectangular.Discharge through a sharp-edged orifice may be calculated from:
Q = Ca?2gh
whereQ= discharge, ft3/s (m3/s)
C =coefficient of discharge
a =area of orifice, ft2 (m2)Flow Through Slotted Pipe
g =acceleration due to gravity, ft/s2 (m/s2)
h =head on horizontal center line of orifice, ft (m)
The coefficient of discharge C is the product of the coef- ficient of velocity Cv and the coefficient of contraction Cc. The coefficient of velocity is the ratio obtained by dividing the actual velocity at the vena contracta (contraction of the jet discharged) by the theoretical velocity. The theoretical velocity may be calculated by writing Bernoulli’s equation for points 1 and 2.ThusFlow Through Slot Orifice
V2= ?2gh
The coefficient of contraction Cc is the ratio of the smallest area of the jet, the vena contracta, to the area of the orifice.
Submerged OrificesFlow Through Slotted Pipe
Flow through a submerged orifice may be computed by applying Bernoulli’s equation to points 1 and 2 in figure belowAir Flow Through Rectangular Slot
Values of C for submerged orifices do not differ greatly from those for nonsubmerged orifices.
