Heat transfer improvement and pressure drop during condensation of refrigerant-based nanofluid; an experimental procedure

In this paper we have studied the magnetohydrodynamic (MHD) mixed convection Maxwell flow of an incompressible nanofluid with magnetic field and heat transfer over a moving plate aligned horizontally. Thermal radiation has also been applied in order to investigate its effects on velocity and temperature variations in the fluid. The Caputo time derivative has been employed to derive the mathematical model. A numerical solution has been obtained using finite difference discretization along with L1-algorithm. Fractional and other pertinent physical fluid parameters like magnetic field parameter, thermal radiation, effect on velocity, and temperature distribution are analyzed and demonstrated through graphs.

“…Shashikumar et al have examined the impact of SWCNT and MWCNT on magnetohydrodynamic (MHD) Brinkman‐Forchheimer flow in a microchannel with multiple slips. Some further novel studies on nanofluids are presented in Refs . In recent years, many authors have given their much concentration to the microfluidics, in view of its wide scope of utilization in science and engineering viz microheat exchanger, micromixers, MHD micropumps, fuel cells, cooling systems for microelectronic devices, microturbines, and so forth.…”

This communication examines the impact of carbon nanotubes (single-wall carbon nanotubes [SWCNT] and multi-wall carbon nanotubes [MWCNT]) on magnetohydrodynamic Brinkman and Forchheimer flow in a planar microchannel with multiple slips. Flow through a porous medium is modeled via Brinkman and Forchheimer theory. The impacts of thermal-dependent heat source (THS) and exponential space-dependent heat source (ESHS) are deployed. Aspects of Joule and viscous dissipations are also retained. The dimensionless equations are solved using the Runge-Kutta-Fehlberg joint with shooting methodology. The significance of various nondimensional parameters on the flow distributions as well as skin-friction and Nusselt number is illustrated and analyzed. Closed form solution of momentum quantity is developed for a particular case. Obtained numerical results are in perfect agreement with analytical results. Further, the results of SWCNT and MWCNT are compared.

An investigation is carried out to discuss the heat transfer mechanism to an electrically conducting viscous fluid on a curved stretching/shrinking surface incorporated with convective boundary condition. The impact of uniform magnetic field is also considered. The mathematical formulation for the transport of heat and flow phenomena is developed by utilizing a curvilinear co-ordinates system. The obtained sets of PDE are reconstructed into coupled non-linear differential equations by incorporating similarity transformations. The numerical solution is attained by employing the shooting method. The obtained solutions are then used to discuss the impacts of various emerging parameters on the temperature and heat transfer across the surface. Dual nature of the solutions are obtained for definite range of convective, suction, magnetic, Prandtl number and stretching or shrinking parameters. Comparison of the obtained results with the existing results for a flat sheet is found in acceptable agreement. It is noticed that with an increment in convective parameter increases the temperature of the fluid, while an increase in suction and magnetic parameters decreases the temperature of the fluid for both the solutions.
