Special Issue Information

Dear Colleagues,

Boiling heat transfer is an efficient heat transfer mode compared to convective mode due to the latent heat of vaporization during the boiling process. The demand for using a high performance of cooling liquids when applying high or ultra-heat flux makes the scientists of heat transfer think about new passive and active enhancement methods to increase the cooling efficiency. Nanofluids are a new class of cooling liquids that could use instead of traditional fluids such as water, oil, and ethylene glycol with aims to increase the thermal properties especially, the thermal conductivity of those liquids. During the boiling of nanofluids, there is always an ability to deposit the nanomaterial on the heater surface resulting in the nanoporous coating layer in different locations depending on the heater geometry, metal type, and arrangement. The formed nanostructure layer could play an important role to increase or decrease the heat transfer performance through the boiling process. Understanding and characterizing the deposition of nanolayer on the heating element is very crucial to think about the real-life applications of using nanofluids as a promising cooling liquid through the boiling phenomenon. This special issue planned to receive works including, but not limited to investigate the following issues:

  • Deposition of nanomaterials during the boiling process of nanofluid (mono nanofluids, Hybrid nanofluids, and Tri nanofluids).
  • Studying the mechanism of nanolayer formation on the heated surface.
  • Studying the Surface modification after boiling test of nanofluid and making a comparison with the smooth surface before boiling phenomenon.
  • Characterization of the nano-coating layer using different techniques.
  • Studying the nano-coating layer formed by electrochemical coating methods.
  • Studying the heat transfer performance of nano/ or conventional fluids during the convection and boiling modes using nanostructured surfaces.

The heat-transmission characteristics of Co ferrofluid and SiO2−water nanofluid are compared numerically inside enclosures including a heat-generating body. Using the finite-volume method, a steady laminar incompressible flow in two dimensions is solved. The numerical study is conducted to determine the impacts of the solid volume fraction (φ=0.02,0.1 and 0.2), the temperature-difference ratio (ΔT*=0,4 and 20), and the Rayleigh number (Ra=105,106 and 107) on both SiO2−water nanofluid and Co ferrofluid, respectively. In consideration of isothermal and streamlines contours, the aspects of temperature transmission and fluid flow are addressed. It is shown that there is no remarkable difference in the convection rate for both the fluids while increasing the Rayleigh number and temperature difference ratio. Full article

This manuscript contains the modeling and analysis of an unsteady Carreau fluid with a magnetohydrodynamical effect over a stretching sheet. The governing momentum and energy equations admit a self-similarity solution. The system of ordinary differential equations has been solved analytically by the homotopy analysis method (HAM) and numerically by BVP4C (Matlab routine). An analysis of results shows that obtained analytical and numerical solutions are in excellent agreement with existing results in the literature. Furthermore, the effect of various fluid parameters on the velocity and temperature profiles are studied graphically. It is observed that velocity increases in the stretching sheet for power law index n and the Weissenberg number We, whereas it decreases for magnetic parameter M2. Tabular analysis on skin friction and heat transfer rate is also presented against pertinent fluid parameters. Full article
