| Abstract: | The goal of this article is to present a new heater design which combines a thin-film resistometry technique with a double-incident liquid-crystal film in the form of a coated (printed) sheet to provide both a spatial mean surface temperature and a color/ temperature map. The heater is demonstrated to yield spatial temperature results consistent with those of other boiling studies in the literature while providing the additional functionality of a mean temperature measurement. The heater design and calibration are outlined and four boiling tests are presented to show the applicability of such a neater for fundamental boiling research, including some information in the conduction and convection regimes, electric-field-enhanced boiling research, and microgravity boiling research. |
