Modeling of skin tissue heating using the generalized dual phase-lag equation

Archives of Mechanics, 2015
This paper concerns the numerical modeling of skin tissue heating. To describe the analyzed process the system of three generalized dual phase-lag equations corresponding to the successive layers of the skin: epidermis, dermis and sub-cutaneous region is

Climate-adaptive building envelopes: Benchmarking thermochromic coatings against static cool surfaces under future warming and occupancy scenarios

Case Studies in Thermal Engineering
Buildings use energy for cooling and heating to maintain indoor thermal comfort. Owing to rising temperatures and climate change, future energy demand for space cooling is expected to increase, whereas space heating requirements in winter may decline ...

Experimental investigation of abrasive potential and drilling efficiency at elevated temperatures via Cerchar rock scratching

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
To see if and how abrasive potential as well as drilling efficiency change due to rock heating, Cerchar scratch tests were performed on six types of rock at eight temperature levels. Results indicate that rock abrasivity is temperature-dependent.

Forced heat loss from body surface reduces heat flow to body surface [PDF]

Journal of Dairy Science, 2010
Heat stress is commonly relieved by forced evaporation from body surfaces. The mode of heat stress relief by heat extraction from the periphery is not clear, although it reduces rectal temperature. Radiant surface temperature (Ts) of the right half of the body surface was examined by thermovision in 4 lactating Holstein cows (30 kg of milk/d) during 7 ...
