The study concluded that the … Web9 jun. 2024 · The downpull coefficient was defined as a function of the lip angle and gate opening. The function is combined with unsteady flow one-dimensional mathematical model, which based on the integral energy and continuity equations. The downpull force was evaluated for both cases of stationary and closing modes.
