“…The Maxwell fluid flow with the effect of homogeneous–heterogeneous reactions between two revolving disks and heat conduction was scrutinized by Ahmed et al 22 . Also, a numerical study has been fulfilled to explore the fluid and thermal behaviors in different shaped enclosures filled with an Al 2 O 3 /water nanofluid and with a rectangular hot obstacle was investigated by Rashidi et al 23 – 25 .…”

The thermal management of the flow of the hybrid nanofluid within the conical gap between a cone and a disk is analyzed. Four different cases of flow are examined, including (1) stationary cone rotating disk (2) rotating cone stationary disk (3) rotating cone and disk in the same direction and (4) rotating cone and disk in the opposite directions. The magnetic field of strength $$B_{0}$$ B 0 is added to the modeled problem that is applied along the z-direction. This work actually explores the role of the heat transfer, which performs in a plate-cone viscometer. A special type of hybrid nanoliquid containing copper Cu and magnetic ferrite Fe3O4 nanoparticles are considered. The similarity transformations have been used to alter the modeled from partial differential equations (PDEs) to the ordinary differential equations (ODEs). The modeled problem is analytically treated with the Homotopy analysis method HAM and the numerical ND-solve method has been used for the comparison. The numerical outputs for the temperature gradient are tabulated against physical pertinent variables. In particular, it is concluded that increment in volume fraction of both nanoparticles $$\left( {\phi_{{Fe_{3} O_{4} }} ,\phi_{Cu} } \right)$$ ϕ F e 3 O 4 , ϕ Cu effectively enhanced the thermal transmission rate and velocity of base fluid. The desired cooling of disk-cone instruments can be gained for a rotating disk with a fixed cone, while the surface temperature remains constant.

“…Shenoy et al [15] also introduced forced convective flow and heat transfer characteristics in a wavy horizontal channel. Rashidi et al [16,17] studied the condensation flow inside rough and smooth nanochannels by attaching the roughness on the lower walls and investigated the effect of rough surface on the interface properties of the condensation flow for different roughness shapes. Results indicated that the condensation process of flow can be empowered by enhancement of the roughness height.…”

Fully developed laminar flow and heat transfer performance of V-pattern folded core sandwich structures subjected to forced convection are numerically investigated. Based on the periodic feature of folded core, a methodology to simulate the fully developed flow and heat transfer state with a few unit cells is developed. The influences of geometric parameters on the coolant flow resistance and heat transfer behaviour are evaluated. Afterwards, approximate models are established based on design to optimize the heat dissipation efficiency. Design variables considered are geometric parameters of the V-pattern folded core, while the corresponding relative density is taken as a constraint. The simulation results show that the presented methodology makes it possible to analyse the fully developed regime with less computing resources. It is found that both pressure drop and heat transfer rate increase with the tortuosity of the flow channel and the inclination of the folded core. The optimization generates a design with a mildly tortuous feature in the streamwise direction to gain a maximum of heat dissipation efficiency under the current conditions.

“…The nanoparticles used in their work improve the quality of heat transfer. Rashidi et al 14 studied the condensation flow inside smooth and rough nanochannels by attaching the roughness to the lower walls using the molecular dynamics method. The numerical results show that the roughness shape and height of the configuration domain influence the condensation and flow characteristics.…”

This study focuses on the cooling of three heated obstacles with different heights mounted on the bottom of the channel wall using different aspects that influence the enhancement of the heat exchange, as is known in the concept of cooling electronic devices. The lattice Boltzmann method associated with multiple relaxation times (LBM-MRT) was adopted to simulate the physical configurations of the studied system. In
