The equations proposed for the mass fluxes 100 <Gkg/m2.s<2500 at different pressure 100,400 and 800kPa were validated. According to correlation coefficients, the mass flux and tube length have the greatest effect on the CHF increase and decrease, respectively. For the convenience of using the correlations, there is no need to calculate the nanofluid properties and the CHF can be predicted based on the volumetric concentration of the nanoparticle in the nanofluid. In this study, one general and one binary model were presented. The former model was for all channels and the latter had two nonlinear correlations for larger micro-channels and tubules. Based on all available experimental data, the nonlinear model has an error of about 15, and the non-linear binary model has an error of 3. Considering the results obtained for micro-channels, the accuracy of the binary model was about 4. The greatest correlation error was observed for CHF<400kW/m2.]]>
