Characterization of light-induced, volumetric steam generation in nanofluids

► Nanofluids (nanoparticles in water) as solar thermal harvesting mediums. ► Ag, graphite best in experimental results. ► High localized temperature gradients seen - above 1,000,000 °C/m. ► Volumetric boiling - low heat transfer coefficients vs. surface boiling ► High potential for solar direct, volumetric systems.
