Heat transfer characteristics
Pool boiling heat transfer
|Abstract:||The main focus of the present study is to investigate the pool boiling heat transfer characteristics of nanofluids on the cylindrical surface. The nanofluids with suspending TiO2 nanoparticles in the base fluid refrigerant R141b and ethyl alcohol are used as working fluids. Effects of nanoparticle concentration and boiling pressure on the pool boiling heat transfer coefficient on the cylindrical brass surface and the boiling bubble characteristics are considered. It is found that the nanoparticle concentration and boiling pressure have a significant effect on the pool boiling heat transfer coefficient. In addition, the pool boiling heat transfer coefficients obtained from the experiment are compared with the proposed correlation and reasonable agreement is obtained. © 2014 Elsevier Ltd.|
