The present paper is aimed at studying the effect of gravity on the general model of the equations of the generalized thermomicrostretch for a homogeneous isotropic elastic half-space solid whose surface is subjected to a Mode-I crack problem. The problem is in the context of the Green and Naghdi theory (GN). The normal mode analysis is used to obtain the exact expressions for the displacement ...

h this paper, we use a generalized Fourier series to approximate the solution of a boundary value problem describing the torsion of an elliptic micropolar beam. We provide an example demonstrating the effect of material microstructure. @ 2004 Elsevier Ltd. All rights reserved.

These days, heat transfer plays a significant role in the fields of engineering and energy, particularly biological sciences. Ordinary fluid is inadequate to an efficient manner, therefore, several models were considered for betterment transfer. One most prominent single-phase nanofluid model. The present study devoted solving problem micropolar with model channel numerically. governing partial...

The heat and mass transfer of the unsteady flow a micropolar fluid over curved stretching surface was considered in this study. Brownian motion thermophoresis effects were explored analysis. suction/injection cases on discussed. Under assumptions, mathematical model designed employing boundary layer approximations using partial differential equations. A suitable transformation developed lie sym...

The influence of Coriolis body force, electro-magnetohydrodynamics (EMHD) and thermal radiative heat transfer on the Casson hybrid mixed convection nanofluid driven by an exponentially accelerated plate adjacent to a porous medium in rotating system is analyzed. Hybrid (Ag- Al2O3) Al2O3nanofluids are considered with ethylene glycol (EG) base fluid. Maxwell-Garnett model has been deployed derive...

This paper addresses entropy generation in the flow of an electrically-conducting couple stress nanofluid through a vertical porous channel subjected to constant heat flux. By using the Buongiorno model, equations for momentum, energy, and nanofluid concentration are modelled, solved using homotopy analysis and furthermore, solved numerically. The variations of significant fluid parameters with...

The aim of the paper work is to investigate and predict the static performance of journal bearing in turbulent flow condition considering micropolar lubrication. The Reynolds equation has been modified considering turbulent micropolar lubrication and is solved for steady state operations. The Constantinescu’s turbulence model is adopted using the coefficients. The analysis has been done for a p...
