On the Onsetof Thermal Instability in a Low Prandtl Number Nanofluid Layer in a Porous Medium

Journal of Applied Fluid Mechanics, 2015
Thermal instability in a low Prandtl number nanofluid in a porous medium is investigated by using Galerkin weighted residuals method for free-free boundaries. For porous medium, Brinkman-Darcy modelis applied.

RSM‐Based Optimization and Sensitivity Analysis of Radiative MHD Tangent Hyperbolic Nanofluid Flow Over an Exponentially Stretching Porous Sheet With Variable Heat and Mass Fluxes

Engineering Reports, Volume 8, Issue 10, October 2026.
The viscous flow of an incompressible hydromagnetic tangent hyperbolic nanofluid over an exponentially stretching porous sheet is investigated, incorporating variable heat and mass fluxes, Brownian motion, thermophoresis, and thermal radiation. Governing PDEs are transformed into ODEs via similarity transformations and solved numerically using MATLAB's

Enhanced Prediction of Heat Transfer and Frictional Drag Analysis in MHD Fluid Flow Using Fuzzy α‐Cut Parametric Sensitivity Analysis

Engineering Reports, Volume 8, Issue 10, October 2026.
The MHD Williamson fluid flow across a stretching surface is investigated under parametric uncertainty utilizing triangular fuzzy numbers. Fuzzification provides smoother transitions and better predictions of velocity, temperature, skin friction, and heat transfer than traditional crisp models.

Signal‐To‐Noise Ratio Approach for Optimizing Heat Transfer Enhancement in Off Centered Stagnation Point Flow of an Incompressible Tetra‐Hybrid Nanofluid

Engineering Reports, Volume 8, Issue 10, October 2026.
Tetra hybrid nanofluid is a new generation of nanofluid, which consists of four different types of nanoparticles suspended in a base fluid. The multi‐nanoparticles have superior thermal conductivity, improved heat transfer capability, enhanced stability, and better rheological performance than the conventional nanofluids and hybrid nanofluids.
