Optimizing the heat transfer characteristics of MWCNTs and TiO2 water-based nanofluids through a novel designed pilot-scale setup

“…Recently, considerable studies have been dedicated to studying the heat transfer enhancement utilizing nanofluids in different applications such as cooling and refrigeration systems, process engineering, combustion engine, HVAC (heating, ventilation, and air-conditioning), power generation, and mechanical tools, and many others 2 – 4 . Heat transfer and thermophysical characteristics such as viscosity 5 , flash point, thermal conductivity, pour point, heat and mass transfer coefficient, and cooling rate can be enhanced utilizing nanofluids 6 . There is a broad type of nano additives that have been used in the preparation of nanofluids such as metal and metal oxides 7 , 8 , carbon-based nanomaterials 9 , 10 ; however, although they have remarkable features like small size, large surface area, and excellent heat capacity, they tend to be agglomerated, especially at high concentrations.…”

The Synergistic Effect of Intumescent Fire‐Resistive Paint Containing TiO2 Nanoparticles and Chlorinated Paraffin onto Atmospheric‐Metallic Substrates

“…In recent years, the combination of some nano‐fillers with intumescent systems exhibited the considerable potential to increase the smoke suppression and mechanical, thermal, and barrier features of the ingredients with chemical or physical synergistic impacts. There are various nanoparticles for this purpose, such as TiO 2 , [6,7] MWCNTs, [8,9] LDH (nanoclays, layered double hydroxides), SiO 2 , POSS (polyhedral oligomeric silsesquioxane), metal and metal oxides [10–16] . Conventional intumescent additives (i. e., (ammonium polyphosphate, pentaerythritol, and melamine) have excellent expansion and fire‐resistive features [17] .…”

Numerical investigation of TiO2 and MWCNTs turbine meter oil nanofluids: Flow and hydrodynamic properties

“…The shape of the nanoparticles is another crucial parameter; the nanospheres experience more pressure at a given load than the nanoparticles because the former contact surface area is much smaller. Therefore, using layer nanoparticles can minimize the deformation of the wear surfaces [34][35][36][37][38]. Studies have shown that even a small concentration of nanoparticles can effectively improve the tribological properties.…”
