Özet:

 

Nanofluids are colloidal suspensions and have been utilized frequently in heat transfer implementations ranging from heating to cooling. In this study, for numerically specifying the influence of nanoparticle addition inside the base fluid on pool boiling heat transfer, a series of numerical analysis were performed by using hexagonal boron nitride and dichloromethane as nanoparticle and base fluid material, respectively. The nanofluid solution was prepared by doping hexagonal boron nitride nanoparticles into the dichloromethane at the rate of 1.0% (vol.) and Sodium Dodecyl Benzene Sulfonate was added into this solution to prevent nanoparticle compilation during operation. Computational Fluid Dynamics (CFD) approach was preferred and ANSYS Fluent software was used for numerical analysis. In order to be able to make comparison, analysis was performed both dichloromethane and hexagonal boron nitride nanoparticles containing dichloromethane, i.e. nanofluid, solutions. Vapour volume fractions, velocity vectors and contours for each working fluid were determined and discussed.
