Preliminary SWCNTs-kerosene on Carreau MHD flow over a wall with distinct thickness

Abstract

The Magnetohydrodynamics (MHD) Carreau over a stretched surface on a kerosene oil based is examined in this paper. Most specifically, we extended and reported the effects of various parameter namely; magnetic field, thermal radiative and heat generation on the temperature. Thermal conductivity enhancements of water and seawater in the presence of single-walled carbon nanotubes (SWCNTs) are presented. We used transformation of similarity to reduce and regenerated the partial differential equations (PDEs) into ordinary differential equations (ODEs) for the nonlinear governing equation alongside with their related boundary conditions. The result of the regenerated ODEs is solved numerically by the application of the fourth/fifth order Runge Kutta Fehlberg technique with method of shooting using Maple code. The result obtained indicated that there is significant positive correlation between high electric field. The result reported that the temperature parameter is decreased with all parameter when the electric is high (El=0.5), which indicated that the electric filed is a dominant of SWCNTs-kerosene.his study was conducted to develop and study the performance of a Photovoltaic Thermal (PVT) system technology, a system which combines the Photovoltaic (PV) system with a solar thermal (T) system that produces electricity and hot water simultaneously. The objective of this study is to develop a working prototype of the PVT system for roofing system application with water as the cooling agent. A polycrystalline PV cells was used as the solar collector while a transparent rubber tube was attached at the backside of the PV panel with water flowing directly from a water tap source. Two designs were examined for the heat absorber design which was categorized as the parallel and spiral flow design. The system was run at an open space to simulate real life application. A working PVT system was developed; however an electrical efficiency drops 0.3% and 1.07% on the parallel and spiral design respectively when compared to the standard PV system.
