RISAn Improved One-Dimensional Model for Liquid Slugs Traveling in Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An improved one-dimensional (1D) model—compared to previous work by the authors—is proposed, which is able to predict the acceleration and shortening of a single liquid slug propagating in a straight pipe with a downstream ...
Rapid Liquid Filling of a Pipe With Venting Entrapped Gas: Analytical and Numerical Solutions
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The motion of liquid filling a pipeline is impeded when the gas ahead of it cannot escape. Entrapped gas will lead to a significant pressure build-up in front of the liquid column, which slows down the column and eventually ...
Large Eddy Simulation Investigations of Periodic Cavitation Shedding With Special Emphasis on Three-Dimensional Asymmetry in a Scaled-Up Nozzle Orifice
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The periodic shedding of cloud cavitation in a nozzle orifice has a significant influence on the flow field and may have destructive effects. Most of the existing research on the shedding of cloud cavitation in an orifice ...
Dynamic Force on an Elbow Caused by a Traveling Liquid Slug
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The impact force on an elbow induced by traveling isolated liquid slugs in a horizontal pipeline is studied. A literature review reveals that the force on the elbow is mainly due to momentum transfer in changing the fluid ...
Improved One Dimensional Models for Rapid Emptying and Filling of Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Improved onedimensional (1D) models—compared to previous work by the authors—are proposed which are able to predict the velocity, length, and position of the liquid column in the rapid emptying and filling of a pipeline. ...
Fully Coupled Smoothed Particle Hydrodynamics-Finite Element Method Approach for Fluid–Structure Interaction Problems With Large Deflections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a combination of the smoothed particle hydrodynamics (SPH) and finite element method (FEM) solving the complex problem of interaction between fluid with free surface and an elastic structure is studied. A ...

An Improved Positive Displacement Pump Model Accounting for Suction Cavitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Positive displacement (PD) pumps are widely employed in industrial settings due to their inherent simplicity and reliability, serving a variety of applications from slurry transport to jet washing. Although their operational ...
Godunov-Type Solutions with Discrete Gas Cavity Model for Transient Cavitating Pipe Flow
Publisher: American Society of Civil Engineers
Abstract: To simulate transient cavitating pipe flow, the discrete gas cavity model (DGCM) is combined with first-order and second-order finite-volume method (FVM) Godunov-type schemes. The earlier discrete vapor cavity model (DVCM) ...
