Thermal Radiative Flow and Entropy Generation in MHD Williamson Hybrid Nanofluid (Cu+Ag)/H2O Over a Porous Stretching Sheet With Non‐Fourier Heat Flux and Heat Source

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This study investigates the radiative magnetohydrodynamic (MHD) flow of Williamson and hybrid Williamson nanofluids (Cu–water and Cu + Ag–water) over a porous, linearly stretching sheet with suction and internal heat generation. Although nanofluids have been extensively studied, limited research addresses the combined influence of non‐Fourier heat flux,

Mass Transport Analysis in an Annular Microchannel Driven by a Time‐Periodic Oscillatory Electroosmotic Flow for a Maxwell Fluid Under High Zeta Potential

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This study investigates characteristics of the mass transport for Maxwell fluids driven by a time‐periodic oscillatory electroosmotic flow (EOF) in annular microchannels under high zeta potential conditions. A finite difference method is employed to solve the nonlinear Poisson–Boltzmann equation, the Maxwell fluid momentum equation, the convection ...

Soft lubrication: the elastohydrodynamics of non-conforming and conforming contacts

, 2004
We study the lubrication of fluid-immersed soft interfaces and show that elastic deformation couples tangential and normal forces and thus generates lift. We consider materials that deform easily, due to either geometry (e.g.
