A Spatial Decay Estimate for the Hyperbolic Heat Equation
SIAM Journal on Mathematical Analysis, 1996The author derives a spatial decay estimate for an energy functional defined on the solutions of an initial-boundary value problem associated with \(\ddot u+g(\dot u)=\Delta u\), \(\Delta\) the three-dimensional potential operator, an overdot denotes partial differentiation with respect to the time, \(g(s)=c\cdot s\) with a constant \(c>0\).

Time Course of Heat Acclimation and its Decay
International Journal of Sports Medicine, 1998More is known about the time course for the acquisition of human heat acclimation during exercise than its decay or loss. Pioneering research in the 1940s led to our early understanding of the heat acclimation process and its subsequent decay with further knowledge concerning the associated physiological mechanisms in later years.

SEAFP: passive removal of the decay heat
Fusion Engineering and Design, 1995Passive safety is a key issue for the public acceptance of fusion power. Several studies are under way in the European Safety and Environmental Assessment of Fusion Power (SEAFP) program to analyze the possible hazards and the means to keep the system safe.

The decay of the solutions for the heat equation with a potential
Indiana University Mathematics Journal, 2009The authors have studied the large time behavior of the solutions of the Cauchy problem for heat equation with a potential. They classify the decay rate of the solutions and give the precise estimates on the difference between the solutions and their asymptotic profiles. Furthermore, as an application, the large time behavior of the global solutions of

Heat transfer in decaying swirl flows
International Journal of Heat and Mass Transfer, 1975Abstract An experimental study of decaying swirl flows created by tangential vane swirl generators is reported. In the Reynolds number range of 20 000–100 000, an increase in heat-transfer rates of up to 80 per cent is observed. Of all the tangential vane swirl generator configuration parameters, the width has the largest influence on the heat ...

Measurement of Decay Heat and Comparison with Predictions
Nuclear Science and Engineering, 1990The decay heat of Superphenix was measured after reactor shutdown during a 3- to 26-h cooling period. The measurement method, the testing of this method, and the formal calculations are reviewed.

On the spatial decay of solutions of the heat equation
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1971The spatial decay of solutions of parabolic partial differential equations has been the subject of two recent papers by Edelstein [1] and Sigillito [2]. The results obtained by these authors are in some respects analogous to estimates derived in connection with Saint-Venant's principle in the linear theory of elasticity [3], [4].
