This paper examines the forced convection flow of incompressible, electrically conducting viscous fluid past a sharp wedge in the presence of heat generation or absorption with an applied magnetic field. The system of partial differential equations governing Falkner Skan wedge flow and heat transfer is first transformed into a system of ordinary differential equations using similarity transform...

In this study, the optimization and analysis of exergy and thermoelectronics of a combined heat and power generation system, heat and cold with thermal storage for use in a residential complex with an area of ​​147,000 square meters, with the main driving motive of the internal combustion engine. The optimization of the system is based on the annual cost minimization and in two modes of using a...

The present study analyzed numerically magneto-hydrodynamics (MHD) laminar boundary layer flow past a wedge with the influence of thermal radiation, heat generation and chemical reaction. This model used for the momentum, temperature and concentration fields. The principal governing equations is based on the velocity uw (x) in a nanofluid and with a parallel free stream velocity ue (x) and surf...

This program encompassed an analytical and experimental inveSLigdgion 0, the application of passive thermal control techniques to extravehicular flexible space garments in 300 nautical mile earth orbits. Results indicate that passive thermal control by varying the absorptance and emittance of the outer surface of the garment is not possible when internal heat generated is in excess of 1500 Btu/...

Radiation effects on free convection MHD Couette flow of a viscous incompressible heat generating fluid confined between vertical plates have been studied. The governing equations are solved analytically using the Laplace transform technique. The variations of velocity and fluid temperature are presented graphically. It is observed that the velocity decreases with an increase in either magnetic...
