Abstract :

The aim of the present study is to investigate the thermal conductivity, dynamic viscosity, and convective heat transfer of Mg(OH)2-water nanofluid inside a circular tube under turbulent flow. The experiments have been carried in solid volume fractions of 0.0625, 0.125, 0.25, 0.5, and 1%. The results indicated that adding nanoparticles to the base fluid result in noticeable increase in heat transfer rate. Moreover, the results showed that the thermal conductivity is increased while the temperature and solid volume fraction increased.
