Convective heating and cooling of the surfaces find application in process industry. During the heating or cooling cycle of the process, thermodynamic irreversibility which can be associated with the process parameters occurs. Moreover, thermodynamic irreversibility associated with the heating cycle can be quantified through entropy analysis. In the present study, convective heating of the soli...

In this paper, kinetic models are discussed with respect to their uses in describing the intrinsic thermal mortality of insect pests. A unique heating block system was used to obtain kinetic information for the thermal mortality of codling moth larvae. The kinetic data demonstrated the possibility to develop high-temperature-short-time thermal treatments to control codling moth and reduce therm...

The large blood vessels would act as a heat sink and hence plays a significant role during photo-thermal therapy. Gold nanoshell was considered as an high heat absorbing agent in photo-thermal heating to reduce the cooling effect of large blood vessels. In this paper, the thermal history of tissue embedded with large blood vessels during photo-thermal heating were calculated using finite elemen...

The accurate assessment of the thermal conductivity of concretes is an important part of building design in terms of thermal efficiency and thermal performance of materials at various temperatures. We present an experimental assessment of the thermal conductivity of five thermally insulated concrete specimens made using lightweight aggregates and glass bubbles in place of normal aggregates. Fou...

Continuously Heated Greenhouses: A production or retail greenhouse with a constantly maintained temperature of 50 degrees F or more during winter months. Such greenhouse must also have a maintenance attendant on duty at all times or an adequate temperature alarm system to provide warning in the event of a heating system failure. In addition, the greenhouse roof material must have a thermal resi...

Polycrystalline Platinum Nanofilms Q. G. ZHANG, B. Y. CAO, X. ZHANG, M. FUJII and K. TAKAHASHI, J. Phys.: Condens. Matter, 2006, 18, (34), 7937–7950 The thicknesses of the studied polycrystalline Pt nanofilms (1) ranged from 15.0–63.0 nm and the mean grain sizes varied from 9.5–26.4 nm. The thermal conductivities of (1) measured by a direct electrical heating method are greatly reduced from the...

physiologically thermal comfort condition is a limit of temperature and humidity. ,in which thermal control mechanism of human body is in its least activity . thermal comfort conditions not only have impact on sizes of heating and cooling equipment ,but also affects the thickness of insulation, and .energy, consumption of buildings. it is necessary to define thermal comfort condition for differ...

This study investigated thermal ablation and skull-induced heating with a 230 kHz transcranial MRI-guided focused ultrasound (TcMRgFUS) system in nonhuman primates. We evaluated real-time acoustic feedback and aimed to understand whether cavitation contributed to the heating and the lesion formation. In four macaques, we sonicated thalamic targets at acoustic powers of 34-560 W (896-7590 J). Ti...
