Pool Boiling Heat Transfer Characteristics of SiO2 and BN Nanoparticles Dispersed Mono and Hybrid Nanofluids

This study reports an experimental investigation of pool boiling (PB) heat transfer performance hybrid (two types particles) and mono (single-particle) nanofluids consisting Boron nitride (BN) Silicon dioxide (SiO2) nanoparticles (NPs). While (HNFs) were prepared in a total particle concentration 0.05 vol.% with four different percentages these two NPs (are 0.01/0.04, 0.02/ 0.03, 0.03/0.02, 0.04/0.01 (BN vol.%/SiO2 vol.%)), (MNFs) BN SiO2 at the same for each NP type. Both (NFs) base fluid (BF), which is mixture 15 ethylene glycol (EG) 85 distilled water (DW). Then, MNFs HNFs was assessed by experimentation test rig. The obtained results demonstrated good improvements critical flux (CHF) burnout (BHF) both NFs. CHF increased up to 80% BN-based MNF 69% HNF 0.04 BN, maximum percentage into HNF, while lowest improvement 48% SiO2-based compared BF. Similarly, BHF found increase increasing loading enhancement 103% observed. These exhibited significantly improved this BF, it became lower HNFs.
