Energy Science &Engineering, EarlyView.ABSTRACT To investigate the characteristics of a particular self‐priming pump during its typical starting operation, this paper constructs a circulating pipeline system that includes the self‐priming pump, tank, and other components. Initially, air is set up in the upper part of the tank and the self‐priming pump, while the rest of the system is filled

Energy Science &Engineering, EarlyView.ABSTRACT The turbulent flow between coaxial cylinders, particularly when the inner cylinder is rotating, exhibits complex hydrodynamic and heat transfer behaviors critical for various engineering applications. Although many previous studies have simplified these systems with idealized assumptions, real‐world scenarios involve mixed convection and ...

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.

International Journal for Numerical Methods in Fluids, EarlyView.This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables
International Journal for Numerical Methods in Fluids, EarlyView.Based on Hamilton's principle, the study focuses on a novel strategy for the modeling of non‐Newtonian fluids with the help of internal variables. Here, the viscosity evolves locally in space and time. Three configurations are numerically implemented, namely channel flow, a benchmark, and a lid‐driven cavity.

International Journal for Numerical Methods in Fluids, EarlyView.Compared to experimental data of thermophysical properties of NFs, semi‐empirical models cannot estimate FOM correctly. For all working fluids, applying a converging channel instead of the canonical case was inefficient. Diverging channel was always favored compared to the canonical case. For less effective NFs, both lowering the reference velocity and
