2015-8-30 The performance of heat exchangers can be improved to perform a certain heat-transfer duty by heat transfer enhancement techniques. Enhancement techniques can be divided into two categories: passive and active. Active methods require external power, such as electric or acoustic field, mechanical devices, or surface vibration, whereas passive methods do not require external power but make use ...

2017-9-22 The micrograph in Fig. 2 shows the grain structure of a wedge-shaped specimen manufactured at casting rate of 2.8 m/min and temperature of 655°C. Layered structure, characteristic of twin-roll cast material, can be observed over the strip's width. Two zones of fine dendritic microstructure were found in the near-surface regions of the strip while a layer of fine equiaxed grains is seen near ...

(B) Steady-state Snowball aquaplanet on which only meteoric ice is exposed. (C) Non–steady-state Snowball Earth with continents. Meteoric ice-sheet meltwater enters the ocean at ice grounding lines (magenta arrows) but is not balanced by a return flux to the atmosphere–meteoric ice subsystem, because only meteoric ice is exposed.
2015-9-6 Heat transfer and pressure drop characteristics of water based CuO nanofluid inside a horizontal tube were investigated experimentally. The upper limitation of the particle volume fraction with respect to heat transfer performance was also found. CuO-water nanofluids with volume fractions of 0.5%, 1%, 2%, and 4% were prepared by dispersing the CuO nanoparticles with an average diameter

To both ends of a conventionally known C-shaped arm 50, the tube 12 and the detector 14 are each attached. The C-shaped arm 50 can be slided along a curved direction made by its arm body, as shown by an arrow B1, and revolved around its supporting shaft 50a, as shown by an arrow B2, which also permit the tube 12 and the detector 14 to be moved.

2017-4-21 1 Introduction. Natural sources of methane to the atmosphere include sediments submerged in wetlands, lakes, man-made reservoirs, rivers, and oceans, but the magnitude of these emissions remains poorly constrained [Kirschke et al.,
Polymetallic nodules cover large areas of the Pacific and Indian Ocean and have high concentrations of valuable metals, such as copper, nickel, and cobalt ().Exploiting these and other deep-sea metal resources is discussed as an alternative to terrestrial mining to reduce the environmental impacts on vulnerable land ecosystems while accommodating shifting political dependencies (1, 2).
2019-3-23 Carbon fiber can have a broad range of CTE's, -1 to 8+, depending on the direction measured, the fabric weave, the precursor material, Pan based (high strength, higher CTE) or Pitch based (high modulus/stiffness, lower CTE).. In a high enough mast differences in Coefficients of thermal expansion of various materials can slightly modify the rig tensions.
