A Computational Study of MHD Radiative Viscoelastic Nanofluid Over a Stretching Sheet With Thermophoresis and Chemical Reaction

Engineering Reports, Volume 7, Issue 12, December 2025.
A computational model for analyzing heat and mass transfer in MHD viscoelastic nanofluid flow with Brownian motion, thermal radiation and chemical reaction are developed in this work. The findings demonstrate how flow stability, heat transfer, and solute distribution are impacted by these significant physical effects.

Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, Volume 13, Issue 12, Page 6003-6016, December 2025.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.

Research on Oil Cavity Lubrication Characteristics of Sliding Bearings for Wind Turbines With Strong Sudden Change and Heavy Load

Energy Science &Engineering, Volume 13, Issue 12, Page 6183-6192, December 2025.
This paper aims to improve a method to analyze the pressure, bearing capacity, and temperature of different oil cavity shapes with different conditions to enhance the lubrication reliability for wind turbines sliding bearings with discontinuous flow in mixed lubrication wear caused by strong sudden changes and heavy loads.

Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables

International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1457-1481, December 2025.
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.

A Geometric Multigrid Solver for the Incompressible Navier–Stokes Equations Using Discretely Divergence‐Free Finite Elements in 3D

International Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1609-1622, December 2025.
In this paper, we consider the concept of discretely divergence‐free finite elements (DDFFE) based on the Rannacher–Turek finite element pair to efficiently solve the three‐dimensional incompressible Navier–Stokes equations. For this purpose, we first define a spanning set of DDFFE functions and then characterize a set of basis functions for arbitrary ...
