Heat transfer characteristics in partial boiling, fully developed boiling, and significant void flow regions of subcooled flow boiling
(American Society of Mechanical Engineers, 1998-05)Subcooled flow boiling covers the region beginning from the location where the wall temperature exceeds the local liquid saturation temperature to the local where the thermodynamics quality reaches zero, corresponding to ... -
Heat transfer from a moving and evaporating meniscus on a heated surface
(American Society of Mechanical Engineers (ASME), 2003-07)A stable meniscus is formed between a needle dispensing water over a heated circular face of a rotating copper block. The needle is offset from the axis of rotation and thus forms a moving meniscus. The water flow rate, ... -
Heat transfer mechanisms during flow boiling in microchannels
(American Society of Mechanical Engineers (ASME), 2003-04)The forces due to surface tension, inertia, and momentum change during evaporation in microchannel govern the two-phase flow patterns and the heat transfer characteristics during flow boiling. These forces are analyzed in ... -
Heat transfer mechanisms during flow boiling in microchannels
(American Society of Mechanical Engineers, 2004-02)The forces due to surface tension and momentum change during evaporation, in conjunction with the forces due to viscous shear and inertia, govern the two-phase flow patterns and the heat transfer characteristics during ... -
Heats of formation and bond dissociation energies of some simple sulfur- and halogen-containing molecules
(The American Chemical Society: Journal of Chemical and Engineering Data, 1978-04)The heats of formation and bond dissoclation energies of some simple sulfur- and halogen-containing molecules are derived from information found in the literature. These thermochemical quantities are useful in determining ... -
Herpetofaunal species richness responses to forest landscape structure in Arkansas
(Elsevier: Forest Ecology and Management, 2005-05-02)Species accumulation curves were used to study relationships between herpetofaunal richness and habitat characteristics on four watersheds in Arkansas that differed markedly with respect to management intensity. Selected ... -
Heterodyne detection for Fiber Bragg Grating sensors
(Elsveier - Optics & Laser Technology, 2000-07)In this paper, we present a Fiber-Bragg-Grating-based temperature sensor. The technique employs heterodyne detection using two Fiber Bragg Gratings. One of the gratings is used as a reference (local oscillator) and the ... -
Heterogeneity and change in environmental strategy: Technological and political responses to climate change in the global automobile industry
(Stanford University Press, 2002)The formulation of strategy is generally treated as a rational process of matching corporate capabilities to market demands. But this does not always account well for the heterogeneity observed in corporate strategies ... -
Heterogeneous electron-transfer kinetics for some multiply bonded dirhenium complexes
(Elsevier: Journal of Electroanalytical Chemistry, 1985-12-10)Standard electrochemical rate constants kexob have been measured for the two sequential one-electron oxidations of triply-bonded dirhenium(II) complexes Re2X4(PR3)4, where X = Cl or Br, and PR3 = a monodentate tertiary ... -
HI absorption in the gigamaser galaxy TXS 2226-184 and the relation between HI absorption and water emission
(American Astronomical Society, 2002-07-20)We report on the discovery of H i in absorption toward the gigamaser galaxy TXS 2226-184 using the Very Large Array. The absorption appears to consist of two components—one with a width of 125 km s^-1 and one broader (420 ... -
Hierarchical approach to the optimal design of camera spectral sensitivities for colorimetric and spectral performance
(The Society for Imaging Science and Technology and the Society of Photo-Optical Instrumentation Engineers, 2003-01)The optimal design of spectral sensitivity functions for digital color imaging devices has been studied extensively. This paper analyzed the important requirements for designing sensor sensitivity functions. A hierarchical ... -
High accuracy imaging polarimetry with NICMOS
(Astronomical Polarimetry, 2009)The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2 - 1.5%. To better quantify and characterize this residual we obtained ... -
High flux heat removal with microchannels - A roadmap of challenges and opportunities
(American Society of Mechanical Engineers (ASME), 2005-06)Heat fluxes in IC chips and other electronics equipment have reached the current limits of air cooling technology. Some of the applications require heat fluxes well beyond the limit of 100 W/cm2, requiring advanced ... -
High flux heat removal with microchannels — A Roadmap of challenges and opportunities
