Soret-dufour effects on heat and mass transfer of newtonian fluid flow over the inclined sheet and magnetic field

SSPM Isa, HM Azmi, NM Arifin… - Journal of Advanced …, 2023 - semarakilmu.com.my
Newtonian fluid is ideal for lubrication purposes because the viscosity of this fluid remains
as a function of the shear. Besides, the heat and mass transfer are an important study area …

Study on Ultra-Long-Distance Transportable Concentration Gradient of Coal Gangue Slurry with Different Gradations

S Wang, H Yu, R Wu, M Tang, Y Liu, L Liu, X Song - Minerals, 2024 - mdpi.com
Coal gangue, the primary solid waste generated during the coal mining process, is typically
disposed of on the surface, where it gradually accumulates to form gangue piles that …

Direct numerical simulation of roll waves on landslide mudflow

B Yu, VH Chu - Physics of Fluids, 2024 - pubs.aip.org
Roll waves on landslide muds are nonlinear instabilities on non-Newtonian laminar free-
surface flow. Existing theories of the roll waves on the mudflow have been developed using …

Smooth thin-layer asymptotic expansions for free-surface yield-stress flows

D Denisenko, GL Richard, G Chambon - 2024 - hal.science
We derive two asymptotic expansions with a smooth velocity field for free-surface
viscoplastic flows down an inclined plane in the shallow-flow approximation. The first …

A DEPTH-AVERAGED MODEL FOR GRANULAR FLOW CONSISTENT WITH THE INCOMPRESSIBLE µ (I) RHEOLOGY

E Deleage, GL Richard - 2024 - hal.science
We derive a depth-averaged model consistent with the µ (I) rheology for an incompressible
granular flow down an inclined plane. The first two variables of the model are the depth and …
