A review of the state-of-the-art nanofluid spray and jet impingement cooling

Abstract

Nanofluid spray/jet impingement cooling is widespread and finds applications in many scientific and industrial paradigms. Because of these ubiquities of nanofluid spray/jet impingement cooling, this branch of fluid dynamics has attracted great attention from the scientific community. The performance of nanofluid spray/jet impingement cooling very often depends on the nanoparticle concentration, shape, and size of the nanoparticle, as well as the mass flow rate of the nanofluid. These aspects lead to interesting variants of the thermo-hydrodynamic analysis of the nanofluid, which are studied meticulously, and some new functionalities are established such as high heat flux removal capacity, temperature uniformity, lower flow rate demand, and no thermal resistance to the heated test surface. We provide an overview of nanofluid spray/jet impingement cooling with an emphasis on the parametric effects, such as the Reynolds number, jet to test surface distance, the Prandtl number, the confinement of the jets, test plate inclination, and the roughness of the test surface, on the underlying phenomenon. Also, we aptly discuss the essential features of the nanofluid spray/jet impingement cooling, which includes spray properties, cooling fluid properties, substrate properties, and environmental conditions, which affect the heat transfer of spray cooling.

“…B. Mahathish numerically investigates the effects of quadratic variation of density-temperature (quadratic convection) and the quadratic Rosseland thermal radiation using the modified Bongiorno Model (MBM) [ 35 ]. Similar analytical as well as numerical approaches can be seen in [ 36 , 37 , 38 , 39 ] for such different viscoelastic models.…”

Primary breakup of shear‐thickening suspension jet by an annular air jet

“…This process can increase the surface area when the liquid jet breaks up into droplets; thus, the transfer velocity of mass and heat can be accelerated as well as the reaction rate. Therefore, atomization is of great importance in industrial processes and applied in fuel combustion, 1,2 spray cooling and drying, 3–5 production technology of microparticles or nanoparticles, 6–9 and medical technology 10–12 . The atomization process generally includes two parts: the primary atomization and the secondary atomization.…”

Multiple Impinging Jet Cooling of a Wavy Surface by Using Double Porous Fins under Non-Uniform Magnetic Field

“…Applications of jet impingement (J-I) cooling are encountered in diverse thermal engineering systems including solar power, electronic cooling, chemical processing, drying, glass annealing, and many more. The geometrical and operating parameters for jet impingement heat transfer (HT) were explored in many studies including different flow regimes and boundary conditions [1][2][3][4]. Due to the complex interaction between the flow field and pressure gradient, thermal boundaries in complicated geometries make the analysis of the HT very difficult to treat it theoretically.…”
