Characterization of Pressure Pulsation Propagation in a Pump‐Turbine Based on the Same‐Frequency Tracking Method

Energy Science &Engineering, EarlyView.
ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.

Numerical Calculation of the Influence of Working Conditions and Rotational Speed on Pressure Pulsation of a Self‐Priming Pump

Energy Science &Engineering, EarlyView.
To accurately determine the pressure fluctuation characteristics of a specific self‐priming pump, a full three‐dimensional computational model was established, including the S‐tube, impeller domain, volute domain, gas‐liquid separation chamber, front and rear cavities, wear ring clearance, and reflux hole.

Non‐Hydrostatic Model for Simulating Moving Bottom‐Generated Waves: A Shallow Water Extension With Quadratic Vertical Pressure Profile

International Journal for Numerical Methods in Fluids, EarlyView.
In this article, we derive a non‐hydrostatic extension to the SWE to solve bottom‐generated waves along with its pressure relation. This relation is built on a linear vertical velocity assumption, leading us to a quadratic pressure profile, where we alternatively write it so that we can solve it by a projection method without ambiguity due to the ...

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics

International Journal for Numerical Methods in Fluids, EarlyView.
This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.
