Introduction: Dust is continuously lifted from the Martian surface and put into atmospheric suspension. This is well visible during dust devil activity [1] and planet encircling dust storms [2]. The mechanism for the atmospheric dust entrainment has been debated for a long time. Wind stress can easily put dust into suspension under Earth conditions, i.e. at ~1000 mbar surface pressure. In princ...

We analysed the thermodiffusion phenomenon both numerically and experimentally for size-based separation of polystyrene microparticles. For model validation, we followed previously published numerical studies using ANSYS Fluent 2020 R2 software. our experimental analysis, defined a new microchannel geometry that would separate at least two groups particles (5 20 µm). trajectory microparticles i...

an analysis is carried out to investigate the effects of variable chemical reaction, thermophoresis, temperaturedependent viscosity and thermal radiation on an unsteady mhd free convective heat and mass transfer flow of a viscous, incompressible, electrically conducting fluid past an impulsively started infinite inclined porous plate by taking into account the viscous dissipation effects. the g...

In this research, numerical modeling is conducted on free convective flow inside a trapezoidal domain with sinusoidal material and temperature allocations at both inclined boundaries using Buongiorno’s nanofluid. The model considers thermophoresis Brownian activity effects taking place in the flow, as well concentration contours. Non-uniform nanoparticle solid have been imposed surfaces. Top bo...

Abstract The influence of slip parameter, viscous dissipation, and Joule heating parameter on MHD boundary layer nanofluid flow over a permeable wedge-shaped surface was analysed. PDEs the associated conditions were transformed to set non-similar ODEs obtained system equations solved numerically with help spectral quasi-linearization method (SQLM) by applying suitable software. This helps ident...
