WebMay 15, 2024 · The formation of outer bank cells in curved laminar flow is controlled by the Dean number ( De=Re (H/R)^ {0.5}, or De=Re (B/R)^ {0.5}) [ 18, 57 ]. However, for most of bend flows which are of curved turbulent flow, there is still no a quantitative criterion for the formation of an outer bank cell. WebJan 2, 2024 · Jan 3, 2024 at 0:09. 1) Create model of a channel on ANSYS. The channel has bends that produce turbulence that causes a pressure drop that can be obtained in the software. 2) Use this pressure drop as the head loss dh to find the Energy Grad Line slope S of the channel (dh/dx = -S) 3) Use S in the Gradually-Varied flow equation to find the …
