On the example of a thermal scheme waste-distillation vacuum desalination plant, it is considered how heat exchange parameters change depending on time year and region navigation vessel or location plant. The performance plant depends engine temperature sea water, since main cooled by which in turn used to heating battery In this scheme, water heated exchanger, characteristics can be selected s...

Thermal sprayed surface coatings are extensively used for a wide range of industrial applications. In the plasma spray process used in thermal spraying, the temperature of substrate and conduction of heat along the thickness of ceramic oxide coatings (TCOC) play an important role in the bond strength and microstructure of the coatings, which decides its performance and quality. In this study, u...

This paper is devoted to the study of semilinear degenerate elliptic boundary value problems arising in combustion theory which obey the simple Arrhenius rate law and a general Newton law of heat exchange. We prove that ignition and extinction phenomena occur in the stable steady temperature profile at some critical values of a dimensionless rate of heat production. 2000 Mathematics Subject Cla...

The thermal efficiency of a distillation column may be improved by permitting heat exchange on every tray rather than only in the reboiler and the condenser. Thermodynamic length optimizations on discrete systems specify the optimal temperature of each tray and consequently the amount of heat to be added or withdrawn in order to maintain that temperature.

We modified the “Daisyworld” model of Watson and Lovelock to consider the energy balance of vegetation with differing potential to evaporate water vapour across a 2-D landscape. High-resolution spatial fields of surface temperature, latent heat exchange and net radiation are computed using cellular automata (CA). The CA algorithm considers competition between actively transpiring “wet daisies” ...

this work presents the heat transfer characteristics of a new type of porous radiant air heater that operates on the basis of effective energy conversion method between flowing gas enthalpy and thermal radiation. at each layer, the gas and solid phases are considered in non-local thermal equilibrium, and combustion in the porous radiant burner is modeled by considering a non-uniform heat genera...

An analysis of the influence of body weight on the energetics of endotherms has been proposed by McNab (1970). It was based on the observations that (1) when body temperature is constant heat production equals heat loss, and (2) heat loss may be described as the product of thermal conductance and the temperature differential between the body and the environment: M = C(Tb—Ta). This expression wi...
