“…Notice that a similar approach was previously used by earlier researchers [21] and [22] to model the effective thermo-physical properties of the nanoparticle suspension. Such an approach also finds experimental confirmation in the data reported by Xuan and Li [9] for Cu-water and oil-water nano-fluids. The thermophysical properties of the nano-fluids are assumed to be constant .…”

This paper investigates theoretically forced convection from an inclined elliptic cylinder placed in a nanofluid cross laminar flow with constant surface temperature. The nanofluid is created by suspending copper particles in water. The referred problem is studied through solving the conservation equations of mass, momentum, and energy using Fourier spectral method. There are some important parameters affect the heat transfer characteristics which can be presented as follows: Inclination angle which varies from 0 to 90 degrees, and copper nanoparticles volume fraction starts from 0 up to 0.05. these parameters are investigated under the conditions: Reynolds number is 50, elliptic axis ratio is fixed at 0.5, and constant surface temperature. The results are found to be in a good agreement with the previous studies in the same category, for different axes ratios and Prandtl number of 0.7. The conclusions of the present investigation show that when nanoparticles volume fraction increases, an obvious enhancement in heat transfer is produced. On the other hand, when changing the angle of inclination from 0 up to 90 the flow exhibits lower heat transfer rates, and all these results are indicated through calculating average Nusselt number.

“…On the other hand, the company P.A. Hilton Ltd has created a heat exchanger, which has the water called H103G, which consists of concentric tubes where hot water flows and the cooling water flows through the annular space in order to allow students to investigate the behavior of the numbers Reynolds, Prandtl and Nusselt [8], [16].In addition to this, multimedia tools for a better understanding of the phenomena that occur in heat transfer [14]. Amatrol presents a model, CD-11604 which, through attractive interactions and 3D animations accompanied by text and audio, explains the heat transfer by conduction and convection in a more didactic way for the students [1].…”

In order to improve the learning processes in terms of conduction of heat in a transient state, we present in this work the assembly and development of a team whose objective is to determine the coefficients of convection of water and air that cool two cylinders of different material which are copper and steel, these will be subjected to a free convection in the first place and then give way to forced convection, once obtained the data will be made graphs and tables, which will allow comparison of an experimental and theoretical values. In this way the students of the engineering faculty can have a physical experiment on the phenomenon that occur in the heat transfer given during the class, which will allow them to strengthen their knowledge.
