... characteristics, e.g., surface roughness, surface damage, oxide layers, and deposited thin films, and cannot be assumed as those of pure materials, typically referred to optically smooth surfaces (OS). An experimental investigation of the thermal emittance of some metals (nickel, titanium, silver, and stainless...

... in the infrared spectrum. The radiative properties for VACNT thin films are also evaluated, showing some reduction of absorptance in the near-infrared due to transmission for film thicknesses less than 50 μ m. This study provides a better understanding of the infrared behavior of VACNT and may guide the design...

... stability analysis of thin films that surface tension has a stabilizing effect on the film [ 16 , 17 ], and that condensation (opposed to evaporation) tends to stabilize the film [ 18–21 ]. Nonlinear stability analysis for flows along plates has shown that stability of the film depends on the frequency...

... 2 δ 0 2 - d 0 δ 0 ) Equation (30) indicates that the maximum heat flux occurring in the evaporating thin-film region is not greater than 0.47 times of the characteristic flux heat, q ″ 0 = ( k l ( T w - T v...

... performance of circuitry, but the spatial resolutions are nearly equivalent. We have demonstrated utilization of the thermoreflectance technique to acquire temperature difference measurements of self-heating gold thin film structures. The current thermal and spatial resolutions of the measurement...

.... Therefore, Eq. 13 or 14 can be viewed as the local equilibrium condition that should not be imposed in solving EPRT for thin films. Consider a thin film in Casimir’s limit where ballistic phonon transport dominates between two black walls. One may view phonon radiation as being emitted from two...

...Arpit Mittal; Sandip Mazumder The Monte Carlo method has found prolific use in the solution of the Boltzmann transport equation for phonons for the prediction of nonequilibrium heat conduction in crystalline thin films. This paper contributes to the state-of-the-art by performing a systematic study...

... decreases abruptly until f r = 3.5 % , for which its value is minimum and 3.7 times lower than that of the empty system. This abrupt variation is most likely due to the thinning of the liquid film in the grooves at the evaporator and especially to the very thin film at the junction between...

...Jun Yu; Zhen’an Tang; Fengtian Zhang; Haitao Ding; Zhengxing Huang This paper presents a micropulse calorimeter for heat capacity measurement of thin films. Optimization of the structure and data processing methods of the microcalorimeter improved the thermal isolation and temperature uniformity...

...Jeromy Jenks; Vinod Narayanan An experimental study of the absorption of ammonia vapor in a constrained thin film of ammonia-water solution is presented. A large aspect ratio microchannel with one of its walls formed of a porous material is used to constrain the thickness of the liquid film...

In this investigation, hybrid μ P T molecular dynamics (MD) simulations were used to predict the pressure field and film thermophysics for an argon film on a metal surface. The results of the simulations...

...N. Bianco; O. Manca In this paper the transient coupled conductive-radiative field, due to a laser heat source impinging on a thin film deposited on a substrate, has been solved in the hypothesis of one dimensionality of the optical field and of two dimensionality of the thermal field. Results have...
