Theoretical analysis of pool boiling characteristics of Al2O3 nanofluid according to volume concentration and nanoparticle size

To investigate the effect of volume concentration and nanoparticle size on nanofluid boiling, a simulation with various concentrations of nanofluids and nanoparticle sizes was carried out using the HFP (heat flux partitioning) model with variations in the contact angle. The CHF (critical heat flux) of the nanofluid rose more than the base fluid. When the volume concentration was 0.025 vol% and the size of the Al2O3-nanoparticles was 50 nm, the...
