        The experimental study on the boiling heat transfer performance and visualization of Al2O3-H2OSiO2-H2OandAl2O3-SiO2-H2Onanofluidswith0.01%massconcentrationwerecarriedout.Aluminaandsilicananoparticleswithaverageparticlediameters of30nmand50nmwereselected.Al2O3-SiO2-H2OwasthemixedaqueousnanofluidswithamassratioofAl2O3 toSiO2 of1:1.Theresultsshowthattheeffectofparticle size on the boiling heat transfer performance is small. For nanofluids with a particle sizeof30nm,theboilingheattransferperformanceofAl2O3-H2Onanofluidsisbetter than that of Al2O3-SiO2-H2O and SiO2-H2O nanofluids under the working pressure of 101 kPa. The critical heat fluxes increased by 7.9% and 22.1% respectively, and the maximum heat transfer coefficients increased by 18.3% and 32.6% respectively. Thecriticalheatfluxandthemaximumheattransfercoefficientare162.1W/cm2 and 7.01W/(m2·K).Theworkingpressurehasanimportanteffectontheboilingheattransfer performance of nanofluids. Compared with the boiling heat transfer performance under high pressure conditions, the boiling heat transfer performance of nanofluids is better under low pressure.
