• The objective of this work is to measure spatial and temporal heat flux variation during nucleate pool boiling of R113/R11 mixtures using a microscale heater array in conjunction with a high speed CCD. The microscale heater array is constructed using VLSI techniques, and consists of 96 serpentine platinum resistance heaters on a transparent quartz substrate. Heat flux data around an isolated bubble are obtained with triggered CCD images. The heat transfer variation vs. time on the heaters directly around the nucleation site is plotted and correlated with images of the bubble. For both of the mixture and pure system, the wall heat fluxes are presented and compared to find out the qualitative difference between pure and binary mixture nucleate boiling. The bubble diameters were measured around half of the van Stralen's model. The sharp heat flux increase was observed for the pure liquid, however it was not for the mixture liquid.
