The effect of variable thermal conductivity on the characteristics heat transfer and mechanical properties a moving surface Casson nanofluid flow as coolant has been studied in this paper. We used similarity transformation method to transform equations governing boundary-layer into ODE which are solved numerically using mix fourth order Runge-Kutta find root technique. Different values relevant...

In this study, enhancements of thermal conductivities of ethylene glycol, water, and synthetic engine oil in the presence of copper (Cu), copper oxide (CuO), and multi-walled carbon nanotube (MWNT) are investigated using both physical mixing method (two-step method) and chemical reduction method (one-step method). The chemical reduction method is, however, used only for nanofluid containing Cu ...

A boundary layer flow of Casson nanofluid passing through a heated slab due to Newtonian heating with inconstant viscosity streaming over varying surface thickness is investigated. The fluid equations which are non-linear PDE converted ODE by suitable similarity transformation. numerical approach used solve those along several values pertinent parameters such as the velocity power constant m, m...

It is well known that solar energy the main source of thermal coming from sun responsible for huge operations in engineering studies. can be seen technology photovoltaic cells, streetlights, plates, and water pumping. This study investigating radiation as a method to improve performance pump (SWP) with use along nanotechnology. The transfer checked case many impacts including heat radiations va...

A theoretical model for nanofluid flow, including Brownian motion and thermophoresis, is developed and analysed. Standard boundary layer theory is used to evaluate the heat transfer coefficient near a flat surface. The model is almost identical to previous models for nanofluid flow which have predicted an increase in the heat transfer with increasing particle concentration. In contrast our work...

For a solar thermal system, increasing the heat transfer area can increase the output temperature of the system. However, this approach leads to a bigger and bulkier collector. It will then increase the cost and energy needed to manufacture the solar collector. This study is carried out to estimate the potential to design a smaller solar collector that can produce the same desired output temper...
