The pipeline transportation of coal slurries is always subject to a temperature difference between the outdoors environment and fluid body. As slurries’ viscosity typically dependent, flow accompanied by heat transfer. In this study, we used CFD method investigate distributions structures in straight curved channels, which has not previously been investigated, according our knowledge. First, re...

The dynamics of dense finite-size particles in vertical channel flows Newtonian and viscoelastic carrier fluids are examined using particle resolved simulations. Comparison to neutrally buoyant the same configuration highlights effect settling. volume fraction is $5\%$, a gravity field acts counter flow direction. Despite modest density ratio ($\rho_r = 1.15$), qualitative changes arise due rel...

Microfluidics is used increasingly for engineering and biomedical applications due to recent advances in microfabrication technologies. Visualization of bubbles, tracer particles, and cells in a microfluidic device is important for designing a device and analyzing results. However, with conventional methods, it is difficult to observe the channel geometry and such particles simultaneously. To o...

In the present work, entropy generation in the flow and heat transfer of couple stress fluid through an infinite inclined channel embedded in a saturated porous medium is presented. Due to the channel geometry, the asymmetrical slip conditions are imposed on the channel walls. The upper wall of the channel is subjected to a constant heat flux while the lower wall is insulated. The equations gov...

Peristaltic transport of copper-water nanofluid in an inclined channel is reported in the presence of mixed convection. Both velocity and thermal slip conditions are considered. Mathematical modelling has been carried out using the long wavelength and low Reynolds number approximations. Resulting coupled system of equations is solved numerically. Quantities of interest are analyzed through grap...

This study deals with the numerical solution of a 2D unsteady flow of a compressible viscous fluid in a channel for low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes, nearly closing the channel during oscillations. The flow is described by the system of Navier-Stokes equations for laminar flows....
