The present work is concerned with unsteady two-dimensional laminar flow of an incompressible, viscous, perfectly electrically conducting fluid past a nonisothermal stretching sheet in the presence of a transverse magnetic field acting perpendicularly to the direction of fluid. By means of the successive approximation method, the governing equations for momentum and energy have been solved. The...

The purpose of this study was to develop a new use for microbial cellulose produced by the bacterium, Acetobacter xylinum. There is a potential application of bacterial cellulose to construct a nano-scale laminar flow reactor. Small particles (i.e. enzymes or solid phase reactants) can be embedded in a growing cellulose matrix with geographic specificity. A fluid containing a substrate can then...

Numerical simulation and experimental investigation were used for study of laminar forced convective heat transfer of Al2O3/water nanofluid. Single phase model with temperaturedependent properties was employed for numerical simulation of transport phenomena in nanofluid. The results of experiments and computer-aided simulation indicated remarkable enhancement of convective heat transfer of base...

This paper reports the numerical determination of the entropy generation due to heat transfer, mass transfer and fluid friction in steady state for laminar double diffusive convection, in an inclined enclosure with heat and mass diffusive walls, by solving numerically the mass, momentum, species conservation and energy balance equations, using a Control Volume FiniteElement Method. The influenc...

The problem of compressible boundary-layer laminar flow of a particulate suspension over a semi-infinite fiat plate is solved numerically using the finite-difference methodology. The mathematical model employed includes such effects as particle-phase viscous stresses, variable position-dependent particle slip coefficient, and general power-law viscositytemperature and thermal conductivity-tempe...

The purpose of the present paper is to study an unsteady laminar flow and heat transfer of an incompressible, conducting viscous dusty fluid between two infinitely non-conducting parallel plates. The flow is influenced by pulsatile pressure gradient, uniform magnetic field which is applied perpendicular to the plates and due to oscillations of the plates. The governing partial differential equa...

Lubricant-impregnated surfaces (LIS), where micro/nanotextured surfaces are impregnated with lubricating liquids, have received significant attention for their robust, superslippery properties. In this study, we systematically demonstrate the potential for LIS to reduce drag in laminar flows. We present a scaling model that incorporates the viscosity of the lubricant and elucidates the dependen...

Results are presented from a series of analytical and numerical studies of buoyantly driven flows along heated vertical surfaces immersed in stably stratified fluids. Flows of the studied type are broadly represented in engineering and geophysical applications. First, the classical problem of one-dimensional natural convection flow along a heated wall is revisited for the case of a stably strat...

Fluid flows have been studied systematically for more than a century and their equations of motion are well known, yet the transition from laminar flow to turbulent flow remains an enigma. The difficulty lies in the intractability of the nonlinear hydrodynamic equations that express the conservation of mass, momentum and energy for a fluid continuum. Although these equations can be linearized a...
