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

open access: yesEngineering 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.
