This work studies the influence of phoretic motion (thermophoresis and diffusiophoresis) fine alumina particles (“smoke”) produced during combustion aluminum. Direct numerical simulations on a single aluminum droplet burning in quiescent environment suggest that thermophoresis is main mechanism driving smoke back to surface, hence major contributor oxide lobe development. The presence this foun...

Numerical simulation is performed in this study to explore filmcooling enhancement by injecting mist into the cooling air with a focus on investigating the effect of various modeling schemes on the simulation results. The effect of turbulence models, dispersed-phase modeling, inclusion of different forces (Saffman, thermophoresis, and Brownian), trajectory tracking, and mist injection scheme is...

The objective of this research is to examine the steady incompressible two-dimensional hydromagnetic boundary layer flow nanofluid passing through a stretched sheet in influence viscous and ohmic dissipations. present problem obtained with help an analytical technique called DTM-Pade Approximation. mathematical modeling considered form partial differential equation transformed into suitable sim...

mhd boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. a system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order rung...

this paper is concerned with asphaltene deposition in fluid flowing through pipelines. brownian diffusion and drag, gravitational, thermophoresis, buoyancy, and shear removal are considered as possible mechanisms in the asphaltene deposition process. the thermo-physical properties of the fluid were obtained from iranian oil fields. a model was used in the pipeline deposition modeling to predict...
