The current study describes three-dimensional incompressible mixed convection flow with convective heat and mass transport on squeezing nanofluid from a rotating channel under impact of Hall current, heat source and Soret number. The current flow model is formulated to consider water based nanofluids with nanoparticle CuO (Copper Oxide). Effectively a nanoscale formulation with the Tiwari-Das model deployed to study material properties. The basic flow equations rendered to non-dimensional form via similarity transformation for which numerical simulations utilizing the fourth-fifth order Runge-Kutta-Fehlberg scheme with the help of Maple, it is a simple iteration scheme that does not require any evaluation of perturbation and linearization for solving non-linear system of equations. Graphical results for primary velocity, secondary velocity, temperature and nanoparticle concentration distributions are presented for different controlled parameters. Furthermore, computed numerical results for skin friction, Nusselt number and Sherwood number for different emerging parameters are tabulated and discussed in detail. The results are verified for limiting cases by comparing with various investigators and found to be in excellent agreement. Outcomes reveal that decrease in secondary flow to a rising channel rotating term and Hall current term. Squeezing term improved the flow rate motion, but reduces nanoparticle conductivity and species diffusion. Thermo-diffusion term stimulated the CuO nanofluid reaction. The authors have hope that the results obtained in the present study not only provide useful information for applications, it also serves as a complement to the previous studies.

“…The use of porous media has emerged as one of the promising passive cooling techniques due to the intensified mixing of fluid streams and large contact surface area to volume ratio. The usage of nanofluid (Gangadhar et al, 2022a(Gangadhar et al, , 2022b(Gangadhar et al, , 2022c(Gangadhar et al, , 2022d(Gangadhar et al, , 2017Venkata Subba Rao et al, 2018) and a flow path with uneven geometry are the other passive cooling techniques. Several research investigations have been carried out on convective heat transfer enhancement techniques using porous media due to its wide engineering applications (Ould-amer et al, 1998;Akbarzadeh et al, 2019;Mehta and Pati, 2021a).…”

Purpose The purpose of this paper is to investigate computationally the hydrothermal characteristics for forced convective laminar flow of water through a channel with a top wavy wall and a flat bottom wall having metallic porous blocks. Design/methodology/approach The governing equations are solved computationally using a finite element method–based numerical solver COMSOL Multiphysics® for the following range of parameters: 10 ≤ Reynolds number (Re) ≤ 500 and 10–4 ≤ Darcy number (Da) ≤ 10–1. Findings The presence of porous blocks significantly influences the heat transfer rate, and the value of local Nusselt number increases with the increase in Da. The value of the average Nusselt number decreases with Da for the top wall and the same is enhanced for the bottom wall of the wavy channel with porous blocks (WCPB). The value of the average Nusselt number for WCPB is significantly higher than that of the wavy channel without porous block (WCWPB), plane channel without porous block (PCWPB) and plane channel with the porous block (PCPB) at higher Re. For PCPB, the performance factor (PF) is always higher than that of WCWPB and WCPB for Da = 10–4 and Da = 10–3. Also, PF for WCPB is higher than that of WCWPB for higher Re except for Da = 10–4. Further, the value of for WCPB is higher than that of PCPB at Da = 10–2 and 10–1 at Re = 500. Practical implications The current study is useful in designing efficient heat exchangers for process plants, solar collectors and aerospace applications. Originality/value The analysis of thermo-hydraulic characteristics for laminar flow through a channel with a top wavy wall and a flat bottom wall having metallic porous blocks have been analyzed for the first time. Further, a comparative assessment of the performance has been performed with a wavy channel without a porous block, a plane channel without a porous block and a plane channel with porous blocks.
