Flow boiling has become a reliable mode of adapting to larger power densities and greater functions because it is able to utilize both the latent and sensible heat contained within a specified coolant. There are currently few available tools proven reliable when predicting heat transfer coefficients during flow boiling in microchannels. The most popular methods rely on semi-empirical correlations derived from experimental data but can only be applied to a narrow subset of testing conditions. This study will use multiple data science methods to accurately predict the heat transfer coefficient during flow boiling in micro-channels on a database consisting of 16,953 observations collected across 50 experiments using 12 working fluids. The support vector machine model performed best, with a Mean Absolute Percentage Error (MAPE) of 11.3%. The heat flux, vapor-only Froude number, and quality proved to be especially significant variables across 90% of over 110 different models.
