A method is developed to capture the distribution of surface temperature while simultaneously imaging the bubble motions in diabatic flow boiling in a horizontal minichannel. Liquid crystal thermography is used to obtain highly resolved surface tempe

An apparatus that produces flow and heat transfer in horizontal narrow channels was used to explore the physics of the onset of subcooled nucleate boiling for R-11 and Novec 649. The apparatus uses a downward-facing electrically-heated thin foil as a

Data resulting from photographic studies of FC-87 vapor bubbles rising under a constant temperature plate are used to describe the growth and motion of the bubbles. Such bubbles are known to cause significant enhancement of heat transfer during their

Flow regimes and bubble growth are observed in a pin-fin micro-scale heat exchanger with R-11 as the working fluid. The heat exchanger is machined in silicon and derived from a DNA micro-array consisting of 150 μm-square fins separated by 50 μm-squ

The transition from the onset of nucleate boiling up to fully developed nucleate boiling in a rectangular minichannel was investigated. This transition has been called the “turning angle” phenomenon in the past because it involves a set of heat f

Measurements were made of the effective emittance of three types of radiator coatings as a Martian dust simulant was added to the radiator surfaces. The apparatus consisted of multiple radiator coupons on which Carbondale Red Clay dust was deposited.

A laser-based method has been developed to measure the thickness of the liquid microlayer between a cap-shaped sliding bubble and an inclined heated wall. Sliding vapor bubbles are known to create high heat transfer coefficients along the surfaces ag

Experiments were performed to investigate nucleate flow boiling and incipience in a vertical flow channel, 20mmwide×357mmlong, with one wall heated uniformly and others approximately adiabatic. Three channel spacings, 2, 1 and 0.5mm, were investigat

Measurements that illustrate the enhancement of heat transfer caused by a bubble sliding under an inclined surface are reported. The data were obtained on an electrically heated thin-foil surface that was exposed on its lower side to FC-87 and displa
