This analysis examines the flow of Sutterby nanofluid having bioconvection due to a stretching sheet and heated convective boundary condition. The heat sink/source was imposed in terms energy equation. entropy minimization is also considered. Through appropriate transformation system nonlinear PDE’s setting, existing problem has altered into ODEs then numerically utilized via bvp4c method. nume...

A contact/friction isoparametric finite element for the analysis of connections between laminated composite plates is presented. The element is compatible with a three-dimensional plate element based on layer-wise constant shear theory. The contact/friction element is based on a simple regularization of the unilateral contact with an orthotropic Coulomb friction problem. Two different friction ...

This paper aims to perform the second law analysis of thermodynamics on the laminar film condensation of pure saturated vapor flowing in the direction of gravity on an ellipsoid with variable wall temperature. The analysis provides us understanding how the geometric parameterellipticity and non-isothermal wall temperature variation amplitude “A.” affect entropy generation during film-wise conde...

The Problem of peristaltic transport of a fluid with magnetic fluid with variable viscosity through the gap between coaxial tubes where the outer tube is non-uniform with sinusoidal wave traveling down is wall and the inner tube is rigid. The relation between the pressure gradient, friction force on the inner and outer tube are obtained in terms of magnetic fluid and viscosity. The numerical so...

OBJECTIVE This study tests the hypothesis that the natural progression of osteoarthritis (OA) in human joints leads to an increase in the friction coefficient. This hypothesis is based on the expectation that the wear observed in OA may be exacerbated by higher friction coefficients. A corollary hypothesis is that healthy synovial fluid (SF) may help mitigate the increase in the friction coeffi...

Abstarct: Flow through pipes and heating situations find wide applications in industry. Depending on the fluid properties, temperature field in the pipe changes. This in turn results in thermodynamic irreversibility in the flow system. Thermodynamic irreversibility can be quantified through amount of entropy generation in the thermal system. Consequently, in the present study, the influence of ...

The present study examines the entropy generation of graphene nanoplatelet (GnP) suspended in different basefluids, theoretically. GnP water (W), ethylene glycol (EG) and glycol- (EGW, 1:1) was examined under laminar flow state a unit length mini micro-channel 3mm 0.05mm diameter. coefficient conductivity (Ck) viscosity (C?) nanofluid were determined from experimental analysis their order magni...

We present an overview of recent work together with J. Hoffman, A. Logg and R. Scott developing a new approach towards resolving the classical paradox of irreversibility in formally reversible Hamiltonian systems such as inviscid fluid models and particle models. We base our solution on finite precision computation in the form of General Galerkin G2, instead of statistical mechanics, which is t...
