Thermal shape fluctuations at constant energy

Nuclear Physics A, 1990
Abstract The constant energy ensemble is used to calculate statistical shape fluctuations in hot rotating nuclei. Comparisons are made with the constant temperature ensemble.

A Review of Thermal-Radiation Constants

Journal of Fluids Engineering, 1954
Abstract A survey of engineering literature and some of the recent textbooks in heat transfer indicates a lack of knowledge by the authors that the various radiation constants used are no longer valid. The various radiation constants, as reported in the CGS system of units by Birge (3), have been ignored, as well as the recent work of ...

Constant effective thermal conductivity of intumescent coatings: Analysis of experimental results

Journal of Fire Sciences, 2017
This article presents the results of an investigation to obtain the constant effective thermal conductivities of intumescent coatings under the influence of different intumescent coating factors (type of intumescent coating, coating thickness, steel section factor, fire condition), based on the analysis of an extensive collection of fire test data ...

Thermal time constants in differential scanning calorimetry

Thermochimica Acta, 1992
Abstract We have examined thermal gradients in a differential scanning calorimeter. We quantified, as a function of sample heat capacity, the thermal lag, Δ T between sample and calorimeter. We found that Δ T = β(τ x + R 0 C s )+ Δ T c ; where β is the heating rate, Δ T c is a constant, C s is the total heat capacity of the sample and ...

The Thermal Time Constants of Dynamo-Electric Machines

Transactions of the American Institute of Electrical Engineers, 1925
Considering the thermal behavior of a dynamo-electric machine intended for continuous service, its acceptance tests require, at present, only a limiting temperature elevation under a continuous rated load. For the intelligent operation of a machine after it has been put in service, additional information is desirable concerning its thermal behavior ...

The thermal constants of setting concrete

Proceedings of the Physical Society, 1936
The rise in temperature in a large mass of concrete during setting may be considerable, and the shrinkage stresses induced by the subsequent cooling may become large enough to cause cracking. It is, therefore, important to be able to calculate the rise of temperature likely to occur in such a mass.

The Time Decay Constants in Neutron Thermalization

Nuclear Science and Engineering, 1963
We examine herein the decay constants, λk which appear in the modal expansion of the neutron density in a study of the time-dependent thermalization of neutrons.

Number of Thermal Time Constants - nTTC

2017
Thermal Time Constant (TTC) indicates the time required for change of 63.2% of temperature difference. This work develops useful application of TTC for determination of temperature change in buildings. Higher TTC results in slower change of room temperature, contributing to thermal comfort, to quality of the building and to energy conservation.

Is The Thermal Time "Constant" Of A Diode Laser Really Constant?

SPIE Proceedings, 1990
Application of the concept of the thermal time "constant" for a description of the transient thermal behavior of diode lasers is examined in the present paper. This concept rests on the assumption that the lumped-heat-capacity method is applicable in this case what turns out not to be true.

Transient thermal response of enclosures: The integrated thermal time-constant

International Journal of Heat and Mass Transfer, 1965
Abstract A method has been developed for theoretical computation of the integrated thermal time-constant of enclosures, hitherto unknown. The enclosure may consist of any number of different types of composite walls, roof and floor, whether all exposed or some unexposed. It may contain any other internal mass such as furniture.
