Experimental and Numerical Determination of Head Loss Coefficients of Two-Way Surcharged Manholes

“…The Type B manhole had no improvement on the head loss coefficients. The incoming stream was directed upwards by a half bench on the bottom, which resulted in significant turbulence and head loss at the confluence, according to detailed inspections of its functioning [37]. had no improvement on the head loss coefficients.…”

“…Evaluating the accuracy of the used CFD programs and modeling methods is the primary focus of many studies [26,[30][31][32][33][34][35]. A proven CFD model can be used as a design tool to optimize the design of sewer connections [36,37]. The capabilities of the CFD model can be advantageous in providing details of flow structures, such as velocity distribution, turbulence, separation, and flow mixing at sewer connections [27].…”
