RISSpurious Numerical Oscillations in the Preissmann Slot Method: Origin and Suppression
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the source of the spurious numerical oscillations often observed in simulations using the well-known Preissmann slot method and proposes a nonoscillatory numerical fix that can efficiently suppress ...

Profile-Induced Column Separation and Rejoining during Rapid Pipeline Filling
Publisher: American Society of Civil Engineers
Abstract: Water column separation during rapid pipeline filling is numerically explored using a one-dimensional (1D) model that employs the method of characteristics to solve the governing equations and the well-known discrete gas ...
Discussion of “Pressure Surges Following Sudden Air Pocket Entrapment in Storm-Water Tunnels” by Jose G. Vasconcelos and Gabriel M. Leite

Physical Understanding of Sudden Pressurization of Pipe Systems with Entrapped Air: Energy Auditing Approach
Publisher: American Society of Civil Engineers
Abstract: A global energy-auditing approach is used to describe the complex transient flow associated with sudden pressurization of a confined pipe system containing entrapped air pockets. The key concept is that the greatest pressures ...
