“…1 ), respectively. According to previous experimental investigations 19 , 24 , the total energy head in each section of the drop shaft is calculated using the following equations:
Figure 1 Definition of vortex drop shaft: ( a ) side view, ( b ) tangential inlet plan view, ( c ) photograph of the physical model.
in which, z = height from zero elevation (origin bed of the outlet channel), V z = vertical velocity, V t = tangential velocity, P ( r ) = pressure distribution at each section of the drop shaft, r = radial coordinate, R = radius of the vertical shaft, D = diameter of the vertical shaft, b = vortex flow thickness, t = relative flow thickness ( t = b / R ), C = circulation constant, Q = design discharge, e = inlet width at the junction of vertical shaft, g = gravity of acceleration, and β = angle of bottom slope.…”

“…From these investigations, it can be proved that the successful usability of DOE in analysis of experimental research demonstrated optimum values of design dimensionless parameters when constructing vortex structures in the practical applications. In addition, the most recent investigation in which effects of dissipation chamber on the energy losses in the vortex energy was studied 24 . Mahmoudi-Rad and Najafzadeh 24 found that the optimal values of effective parameters (i.e., F r and L / D ) yielded 2.32 and 13.901, respectively; so as to stand the efficiency of flow energy loss at its highest level.…”
