It has been focused to develop the lead free solder alloy by substitute the In in place of Pb in Sn-Pb alloy to reduce the harmful effect of lead in conventional Pb-Sn solder alloy. For development of alloy depend on its thermo dynamical properties. In this study, integral enthalpies of mixing for the molten binary In-Sn system at 757, 809, and 845 K were obtained using a drop calorimeter spanning the whole indium range. Automated motorized dropping equipment was used to drop the element. Then, four pieces of α-Al2O3 were dropped at the falling temperature to calibrate the calorimeter. When the integral mixing enthalpies were compared to the composition, it was discovered that all compositions were exothermic. At xIn ~ 0.55, there was a discernible minimum enthalpy of mixing. There is a small degree of temperature dependence. The enthalpy of mixing was utilised to derive the binary interaction parameters using the Redlich-Kister polynomial. The experimental results are contrasted with the estimated results obtained using the Redlich-Kister polynomial. Its show that they were substantially in good agreement.

Recent years have seen a rise in interest in and usage of thermo-hydraulic research of nano-fluid flow phenomena in a variety of engineering applications. Under uniform heat flux, thermo-physical characteristics of nano-fluid flow in baffle-corrugation rectangular channels have been observed from a numerical standpoint for various Reynolds numbers and different values of the aspect ratio of baffles. Employing the finite volume method, the governing equations have been solved and to visualize the simulation results, fluent software has been employed. Four various types of baffle-corrugation shapes (plane, trapezoidal, isosceles, and triangular) with their interchanged positions have been examined in the present analysis. Different types of base fluids viz., water, glycerin, and ethylene glycol, four distinct forms of nanoparticles, Al 2 O 3 , CuO, SiO 2 , and ZnO are assumed to be transmitted for varying values of volume fractions (D%) and diameter of nanoparticles. From the present study, it is found that in the presence of plane baffle-isosceles corrugation provides the highest average Nusselt number ([Formula: see text]) than the rest of the baffles. It is revealed that SiO 2 nano-fluid provides the highest [Formula: see text] in comparison to other nano-fluids. Further, it is concluded that [Formula: see text] enhances with the enhancement of D%, Reynolds number (Re), height, and pitch of the baffles and is found to decrease as the diameter of nanoparticles increases. This study also indicates that glycerin-SiO 2 provides the highest [Formula: see text] than the rest of the base fluids.
