Recent developments in biomedicine have raised the usage of silver (Ag) nanomaterials in enhancing the ability of drug delivery procedures. Magnetic fields are externally applied to guide the drugs towards a specific target. Peristalsis of nanofluid with variable viscosity is studied here. A porous media with varying porosity and permeability becomes saturated with the nanofluid. Temperature dependent viscosity and Maxwell's thermal conductivity models are adopted. Thermal and velocity slip constraints are considered in the study. Low Reynold number and long wavelength predictions are used to simplify governing equations. Simplified non‐dimensional equations are numerically tackled. NDSolve is built in shooting technique that are used in the Mathematica software. Effects of pertinent variables on pressure gradient, velocity, temperature and heat transport process are studied. Addition of silver nanoparticles enhances the heat transport characteristics. The axial velocity is reduced in the existence of an inclined magnetic aspects. Pressure gradient at the wall are increases by increasing the concentration of nanomaterial and magnetic field strength.

“…In addition to the abovementioned regular nanofluids, Akram et al [105][106][107][108][109][110][111][112] conducted a series of numerical investigations with hybrid nanoparticles and inclined magnetic fields, after which they discussed the effects of the different parameters of nanoparticle diffusivity. The results revealed that as a class of novel nanofluids, hybrid nanofluids (e.g., Sisko nanofluids, Jeffreys nanofluid, Oldroyd-4 constants nanofluids, and Prandtl nanofluids) have better thermal effectiveness than regular nanofluids.…”

As one of the most promising thermal management solutions, spray cooling has the advantages of high heat-transfer coefficient and maintaining a low temperature of the cooling surface. By summarizing the influential factors and practical applications of spray cooling, the current challenges and bottlenecks were indicated so as to prompt its potential applications in the future. Firstly, this paper reviewed the heat-transfer mechanism of spray cooling and found that spray cooling is more advantageous for heat dissipation in high-power electronic devices by comparing it with other cooling techniques. Secondly, the latest experimental studies on spray cooling were reviewed in detail, especially the effects of spray parameters, types of working fluid, surface modification, and environmental parameters on the performance of cooling system. Afterwards, the configuration and design of the spray cooling system, as well as its applications in the actual industry (data centers, hybrid electric vehicles, and so on) were enumerated and summarized. Finally, the scientific challenges and technical bottlenecks encountered in the theoretical research and industrial application of spray cooling technology were discussed, and the direction of future efforts were reasonably speculated.

Nanomaterials having excellent thermal properties are employed in producing energy, extrusion processes, engineering processes, nuclear interactions, industrial domains and aero‐spaces, etc. Therefore, current study scrutinizes the aspects of entropy optimization and Ohmic heating on MHD peristalsis of fourth‐grade nanoliquid in a channel. Flexible channel walls retain concentration, thermal slip and velocity conditions. The consequences of viscous dissipation and Arrhenius activation have been accounted. The lubrication approximation is used in mathematical modelling. Nanofluid model is used by considering thermophoresis and Brownian motion. Furthermore, thermal radiation features are included in the energy equation. By using an appropriate similarity transformation, a system of PDEs is simplified to a solvable system of ODEs. Numerical techniques are used to solve the problem of governance. Detailed exploration of the sundry variables of concern on the flow quantities like velocity profile, nanoparticle concentration, temperature and entropy of the system is graphically examined. Heat transfer is examined in tabular form. Based on the derived outcomes, the velocity rises via thermal Grashof and slip variables. Further, an increment in Brownian motion and radiation parameters shows opposite behaviour on temperature.
