An experimental and numerical study of free convection heat transfer from a channel consisting of a vertical sinusoidal wavy surface and a vertical flat plate has been carried out. The vertical wavy surface was maintained at a constant temperature, while the flat plate is adiabatic. A Mach-Zehnder Interferometer was used to determine the local heat transfer coefficients of sinusoidal wavy surfa...

Product innovation is conventionally treated as a mechanism for organizations to renew their product portfolios. In this paper, we suggest that product innovation not only enables organizations to introduce new products to the market but also challenges organizations to renew their technological capabilities. Capability stretching is the degree to which an organization extends its technological...

1. ABSTRACT MHD visco-elastic boundary layer flow problem past a stretching plate with heat transfer is investigated. The basic equations governing the flow and heat transfer are in the form of partial differential equations which have been reduced to a set of non linear ordinary differential equations by applying suitable similarity transfer. The effect of various physical parameter, magnetic ...

A key element in a gait laboratory is a force plate which may be used to measure the forces and moments applied by the foot onto the walking surface during a gait cycle. While many laboratories have relied solely upon motion data as obtained from using various camera techniques for analysis of gait, it is only with the inclusion of a force plate that the dynamic aspects of gait are appropriatel...

In this study, we presented a mathematical model for analyzing the heat source/sink effect on magnetohydrodynamic two-dimensional ferrofluid flow past a cone and a vertical plate in the presence of volume fraction of ferrous nanoparticles. The governing partial differential equations are transformed as ordinary differential equations making use of similarity solutions and solved numerically wit...

An incompressible MHD flow of two-dimensional upper-convected Maxwell fluid over a porous stretching plate with suction is studied. The nonlinear differential equation is solved approximately by means of the Optimal Homotopy Asymptotic Method (OHAM). Multiple solutions are given, showing a very good agreement between the analytical and numerical solutions. This procedure is very efficient in pr...
