“…They also reported that when the massconcentration of the nanoparticles increases, the heat transfers more evenly, and it accelerates temperature uniformity. In another numerical investigation conducted by Rehman et al [23] the thermal enhancement and hydrodynamics characteristics of a confined slot jet impingement for a mixture of NEPCM as a coolant were examined. The water-base coolant was composed 100 nm n-octadecane NEPCM particles.…”

Convective Flow and Heat Transfer of Nano-Encapsulated Phase Change Material (Nepcm) Dispersions Along a Vertical Surface

Nano-encapsulated phase change suspension is a novel type of functional fluid in which the nanoparticles undergo phase change that contribute to heat transfer. Thus, the working fluid carries heat not only by sensible heat but also in the form of latent heat stored in the particles. The natural convection and heat transfer of Nano-Encapsulated Phase Change Materials (NEPCMs) suspensions within a boundary layer along a heated flat surface are theoretically investigated in this work. The nanoparticles are core-shell structured with the core fabricated from PCMs covered by a solid shell. A similarity solution approach along with the finite element method is employed to address the phenomena. The outcomes indicate that a decisive factor in boosting the heat transfer is the temperature at which NEPCM particles undergo the phase transition. The heat transfer parameter can be enhanced by about 25% by just adding 5% of NEPCM particles, compared to the case with no NEPCM particles.

“…It was also observed that the head-on collision of adjacent jets formed a stagnant zone, which produced the weakest local heat transfer on the heating surface. Rehman et al [162] conducted a three-dimensional numerical investigation of confined slot jet impingement by using a slurry of NEPCMs to study hydrodynamic and heat transfer performance. The slurry used had the composition of water as the base fluid, and n-octadecane having a diameter of 100 nm was suspended in it.…”

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.

“…Ho et al [39], [40] performed an experiment to compare the heat transfer enhancement of using either simple alumina nanoparticles or a slurry of phase-change particles in minichannels [40] and tubes [39]. Following [42], [43] and applying some modification, the governing equations for continuity of the mixture, momentum in x and y directions and the heat conservation of the mixture by some modifications can be written as:…”
