Cryocrystallography: effect of cooling medium on sample cooling rate
Journal of Applied Crystallography, 1998The rates of cooling of small samples with cold N2gas (100 K), liquid N2(77 K) and liquid propane (100 K) have been measured. The samples were one bare Cu-constantan thermocouple and one coated with a 0.25 mm layer of silicone rubber cement. Gas cooling yielded the lowest rate, liquid N2the highest.

Measuring the Physiological Effects of Cooling
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1971Men wear cooling garments to reduce external heat load and to remove metabolic heat. The effects of cooling can be seen in physiological measurements made with and without cooling, and the question is: what are the meaningful measurements to make? The following measurements are described and illustrated with experimental data: tolerance times to a ...

Direct sun can generate the same heat as a single bar radiator over each square meter of a surface. Shading can cool up to 90% of this heat. The big problem is that sunlight is a direct source of heat and the radiant heat from the sun passes through glass and is absorbed by building elements and furnishings, which then re-radiate it.

Effects of Curvature on the Film Cooling Effectiveness of Double-Jet Film Cooling
Volume 5B: Heat Transfer, 2014The effect of curvature on the film cooling characteristics of Double-Jet Film Cooling (DJFC) was numerically investigated using three-dimensional Reynolds-Averaged Navier-Stokes (RANS). The low-Reynolds number shear stress transport (SST) model was employed as the turbulence closure model.

The roles of landscape both inside the park and the surroundings in park cooling effect
, 2020Urban heat island effect is much prevailing nowadays with cities expanding. Park cooling island (PCI) is critical to mitigate this effect. Although the cooling effects of greenspace have been known well, the understanding on the roles of landscape inside
