Magnetic Field Effect on Mixed Convection in Lid-Driven Trapezoidal Cavities Filled With a Cu–Water Nanofluid With an Aiding or Opposing Side Wall
Ali J. Chamkha,Muneer A. Ismael +1 more
TL;DR: In this article, the authors investigated mixed convection inside a Cu-water nanofluid filled trapezoidal cavity under the effect of a constant magnetic field and found that the suppression effect of the magnetic field for the aiding case is greater than that for the opposing case.

Numerical Study on Application of CuO-Water Nanofluid in Automotive Diesel Engine Radiator
TL;DR: In this article, the authors investigated the effects of the automotive speed and Reynolds number of the nanofluid in different volume concentrations on the radiator performance and found that the overall heat transfer coefficient and pumping power are approximately 10% and 23.8% more than that of base fluid for given conditions, respectively.

Hybrid lattice Boltzmann-TVD simulation of natural convection of nanofluids in a partially heated square cavity using Buongiorno’s model
TL;DR: In this article, a hybrid lattice Boltzmann (LB) and total variation diminishing (TVD) scheme is proposed, in which the traditional LB method is employed to handle the flow and temperature fields, while the volume fraction equation is solved by a TVD method due to the fact that the corresponding equation is a type of convection-dominated equation.

Experimental and numerical investigation of nanofluid heat transfer in helically coiled tubes at constant wall heat flux
TL;DR: In this paper, the authors focused on numerical and experimental investigation of the laminar, steady state flow in helical tubes with constant wall heat flux boundary condition, and they concluded that using Ag nanofluid increases the heat transfer of helical heat exchangers about 35-38%.

Viscosity, electrical and thermal conductivities of ethylene and propylene glycol-based β-SiC nanofluids
TL;DR: In this article, a two-step technique was used to formulate stable β-SiC nanofluids at room temperature and the experimental results showed that both electrical and thermal conductivity increase while viscosity decreases with temperature.
