Artificial neural networking (ANN) analysis for heat and entropy generation in flow of non-Newtonian fluid between two rotating disks

Tie-Hong Zhao et al.

Summary: Mixed convection is a heat transport mechanism in thermodynamic systems that involves the motion of fluid particles influenced by both gravity and external forces. This study focuses on the mixed convective flow of Ree-Eyring fluid between two rotating disks, considering the effects of porosity and velocity slip. The energy equation is modeled with various factors such as heat generation/absorption, dissipation, radiative heat flux, and Joule heating. The results obtained are compared with previous studies, showing good agreement. Interesting physical phenomena such as skin friction and heat transfer are also numerically calculated.

Combined effect of thermal and hydraulic performance of different nanofluids on their cooling efficiency in microchannel heat sink

Fahad S. Alkasmoul et al.

Summary: This study evaluates the thermal and hydraulic performance of different nanofluids in a microchannel heat sink and finds that nanofluids can enhance its thermal performance. However, considering the flow rate and pumping power, the use of nanofluids deteriorates the heat dissipation efficiency of the heat sink, resulting in no beneficial aspects in terms of thermal performance and energy cost.

Pedram Heidari et al.

Summary: Adhesion is a critical factor in microelectromechanical systems (MEMSs), and this study examines the influence of gold and titanium on adhesion forces. The results show that an AFM tip coated with gold has the highest adhesion force on silicon substrates, while a titanium-coated AFM tip decreases the force. Therefore, these changes must be considered when studying adhesion forces.
