“…Many papers discuss heat transfer applications: For example, a study performed by França et al [9] demonstrated that these new fluids, due to high thermal conductivity and specific heat, are suitable candidates for heat transfer applications in a shell and tube heat exchanger. The same conclusion was also reached by other authors (see, for example, [7,[10][11][12][13][14][15]) that performed mainly numerical studies on heat transfer performance. Anyhow, it was noticed from the archived literature that, at least by these authors' knowledge, the number of experimental studies are scarce.…”

Ionic liquids are a new and challenging class of fluids with great and tunable properties, having the capability of an extensive area of real-life applications, from chemistry, biology, medicine to heat transfer. These fluids are often considered as green solvents. Several properties of these fluids can be enhanced by adding nanoparticles following the idea of nanofluids. These ionic liquids-based nanocolloids are also termed in the literature as ionanofluids or nanoparticles-enhanced ionic liquids. This review summarizes the findings in both areas of ionic liquids and ionic liquids nanocolloids (i.e., ionic liquids with nanoparticles in suspension) with direct applicability in convective heat transfer applications. The review presents in a unified manner the progress and prospects of ionic liquids and their nanocolloids from preparation, thermophysical properties and equally experimental and numerical works. As the heat transfer enhancement requires innovative fluids, this new class of ionic liquids-based nanocolloids is certainly a viable option, despite the noticed drawbacks. Nevertheless, experimental studies are very limited, and thus, extensive experiments are needed to elucidate ionic liquids interaction with nanoparticles, as well as their behavior in convective heat transfer.

“…Heidarshenas et al [58] prepared ionic liquid [BMIM]PF 6 coated Al 2 O 3 nanoparticles at different sizes (20, 50, 80, 135 nm) and then prepared water based nanofluids and studied heat transfer and thermal performance while they flow in a cylindrical microchannel heat sink and they observed Nusselt number enhancement of 26 % at 50 nm relative to water. Ansarpour et al [59] studied the heat transfer of Al 2 O 3 nanoparticles diluted water, ethylene glycol, and 1-ethyl-3-methylimidazolium ethyl sulfate [EMIM][EtSO 4 ] ionic liquid in a horizontal tube of diameter 4.0 mm and length of 6.0 m under constant flux conditions and observed an enhanced heat transfer coefficient compared to the base fluid. Earlier studies revealed that, the heat transfer coefficient of IL nanofluids are enhanced when compared to pure ILs in thermal devices.…”

Due to their improved thermophysical characteristics, such as their strong ionic conductivity, negligible vapor pressure, and thermal stability at high temperatures, the ionic liquids (ILs) are being looked at viable contender for future heat transfer fluids. Additionally, the dispersing nanoparticles can further improve the thermophysical characteristics and thermal performance of ionic liquids, which is one of the emerging research interests to increase the heat transfer rates of the thermal devices. The latest investigations about the utilization of ionic liquid nanofluids as a heat transfer fluid is summarized in this work. These summaries are broken down into three types: (a) the thermophysical parameters including thermal conductivity, viscosity, density, and specific heat of ionic liquids (base fluids), (b) the thermophysical properties like thermal conductivity, viscosity, density, and viscosity of ionic liquids based nanofluids (IL nanofluids), and (iii) utilization of IL nanofluids as a heat transfer fluid in the thermal devices. The techniques for measuring the thermophysical characteristics and the synthesis of IL nanofluids are also covered. The suggestions for potential future research directions for IL nanofluids are summarized.

“…Heat transfer fluid (HTF) is major component of STCs because it's the medium of heat absorb and delivery. Water a conventional base fluid for nanofluids and hybrid nanofluids, in STCs system application, have been studied widely, [14,15] but safety issues arising from the use of inorganic chemically synthesized base fluids and nanofluids use in food, drug and health related industries, as raised health concerns.

Thermal fluids modulate temperature conditions around the thermal collector systems indirectly by circulating the heat transfer fluid throughout the heat exchanger, thereby simulating cooling and heating with thermal condition. This study investigates biofluid from Moringa oleifera kernel, Date kernel, Palm kernel, Coconut kernel and Mango kernel as base fluids for heat transfer fluid application in solar thermal technology. The methodology employed in this study is experimental and the analyzed biofluids results was compared with conventional heat transfer base fluids. Thermal constant analyzer (TPS-2005S), CT-72 Transparent viscometer and Eagle eye SG-500 portable digital hydrometer were used to measure the thermophysical properties, viscosity, and density, of the biofluids respectfully. From the results, the biofluids showed comparative thermophysical properties to conventional base fluids. Moringa oleifera kernel oil and Mango kernel oil has the best quality among the biofluids with thermal conductivity, specific heat, viscosity, and density value was 0.1698Wm/k, 1984.01J/kg.K, 37.12mm2/s, 874.23kg/m3, and 0.2642Wm/k, 763.18J/kg.K, 45.27mm2/s, 914.22kg/m3, respectively. The biofluids was thermally stable after exposure to several heating cycles and heating temperature as no significant degradation was observed in there thermophysical properties. However, there are needs for further experimental studies on clogging and possibility of enhancement of biofluids with organic nanoadditives.
