Abstract :
One of the best ways to enhance heat transfer coefficient is by improving thermal properties of the
working fluid. Gold/water nanofluid flow through horizontal minitube with very low Reynolds number
was simulated by using Thermal Lattice Boltzmann Method (TLBM) under uniform heat flux boundary
condition. The effect of different volume fraction of nanoparticles on the heat transfer coefficient was
studied and compared with the base fluid (water). The results were verified using Finite Volume Method
(FVM). The results showed enhancement of heat transfer coefficient when using gold/water nanofluid
and this enhancement depends on the volume concentration of Gold nanoparticles. The maximum
enhancement was 18% with 0.03 volume concentration.
