Wellbore Flow Behavior and Natural Flow Cessation Prediction in Ultra‐Deep Wells: A Case Study of Shunbei Oilfield

Energy Science &Engineering, EarlyView.
This study develops a framework for predicting flow cessation in ultra‐deep wells, featuring a crude oil property correction model accounting for ultrahigh pressure/temperature effects, a revised liquid holdup model with field‐fitted coefficients, and an integrated pressure drop model coupled with nodal analysis to link reservoir inflow and wellbore ...

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.

The Discretization‐Corrected Particle Strength Method for the Barotropic Vorticity Equations

International Journal for Numerical Methods in Fluids, EarlyView.
Numerical solution for the barotropic vorticity equation in complex geometry using the meshless point collocation method. The spatial domain is represented by a set of nodes. The collocation method numerically solves the strong form governing equations.
