Article Synopsis
  • This research examines the behavior of two shear thinning nanofluids that flow in a micro-channel under various conditions, focusing specifically on aspects like momentum, thermal energy, mass diffusion, and entropy generation.
  • The study finds that the hyperbolic tangent nanoliquid experiences better flow velocity compared to the Williamson nanofluid, although the latter exhibits higher thermal energy and concentration levels.
  • Key parameters such as Grashof number and Schmitt number significantly impact fluid flow rates and the concentration of the nanoliquids, while the temperature jump condition and variable thermal conductivity influence energy distribution and irreversibility within the system.

In this work, double rotating active cylinders and slot nanojet impingement are considered for the cooling system of a conductive panel. Colder surface temperatures of the cylinders are used, while different rotational speeds are assigned for each of the cylinders. The impacts of cylinder rotational speeds, size and distance between them on the cooling performance are evaluated.

A photocatalytic system for decolorization of double azo reactive black 5 (RB5) dye and water disinfection of was developed. Sol gel method was employed for the synthesis of Fe-TiO photocatalysts and were characterized using thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), diffuse reflectance spectroscopy (DRS) and Brunauer-Emmett-Teller (BET) analysis. Results showed that photocatalytic efficiency was greatly influenced by 0.
