Elastocaloric cooling: Stretch to actively cool

Nature Energy, 2016
The elastocaloric effect can be exploited in solid-state cooling technologies as an alternative to conventional vapour compression. Now, an elastocaloric device based on the concept of active regeneration achieves a temperature lift of 15.3 K and efficiencies competitive with other caloric-based approaches.

Actively Controlled Cooling Jets

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A proof-of-concept study has been undertaken to demonstrate the use and potential benefits of actively controlled coolant jets in an IC engine cooling gallery simulator. Results have shown that substantial reductions in coolant volumes are possible and that the control of the liquid/metal surface temperature can be

Thermoregulatory Vasoconstriction Impairs Active Core Cooling

Anesthesiology, 1995
Background Many clinicians now consider hypothermia indicated during neurosurgery. Active cooling often will be required to reach target temperatures < 34 degrees C sufficiently rapidly and nearly always will be required if the target temperature is 32 degrees C. However, the efficacy even of active cooling might be impaired

Evaluation of Horizontal Cooling Channels For Actively Cooled Limiters

Fusion Technology, 1986
The heat flux and fluid flow conditions for a water cooled limiter tube are simulated with an electron beam heating apparatus, and the results are compared to empirical models based on existing heating transfer correlations. For the conditions of highly subcooled flow boiling in a horizontal tube subjected to a heat flux from only one side, two ...

Magnetic Activity in Cool Stars

Space Science Reviews, 1985
Aspects of magnetic activity of late-type stars are reviewed: first, results obtained through the comparison of emissions from various temperature regimes in the outer atmospheres of cool stars, then results from stellar soft X-ray spectroscopy. Spectra obtained with different instruments (Imaging Proportional Counter and Solid State Spectrometer ...

Anomalous Cooling and Overcooling of Active Colloids

Physical Review Letters, 2022
The phenomenon that a system at a hot temperature cools faster than at a warm temperature, referred to as the Mpemba effect, has recently been realized for trapped colloids. Here, we investigate the cooling and heating process of a self-propelled active colloid using numerical simulations and theoretical calculations with a model that can be directly ...
