Experimental results showing the percent increase in (a) critical heat flux (CHF), and (b) heat transfer coefficient (HTC) for bi-conductive surfaces as compared to bare copper surfaces. Optimal performance is seen at Bond numbers of unity with a 2x increase in CHF and a 5x increase in HTC. These results highlights the importance of tuning the wavelength of spatial temperature variations, P, with the capillary length of the working fluid, λ_C, resulting in enhanced boiling performance over all stages of boiling.
