Transient Heat Conduction of Variable Stiffness Composite Laminate

Heat Conduction in Spherical Composite Vessels

This paper presents an exact analytical solution for two-dimensional conductive heat transfer in spherical composite pressure vessels .The vessels are in spherical shape and fibers are winded in circumferential direction. The analytical solution is obtained under the general boundary conditions which consist of convection, conduction and radiation inside/outside of vessel. The heat transfer equ...

Hyperbolic Heat Conduction in Composite Materials

A hyperbolic heat conduction (HHC) equation has been proposed to replace Fourier heat conduction equation in cases heat transfer takes place in a very short period of time or at extremely low temperature. There is a growing interest in the investigation of HHC problem in recent years, but to the author’s knowledge, HHC in composite media in multidimension has not been studied up to date. This p...

Heat conduction through a DNA-gold composite.

This paper reports results from electrical and thermal conduction measurements carried out on the DNA-gold composite for which the overall conduction is shown to be dominated by the DNA rather than the discontinuous gold coatings. The electrical and thermal conductivities of the composite were about 14 S/cm and 150 W/(m K) at room temperature, respectively. The resulting value of 3.6 x 10(-4) W...

Quasiballistc Heat Conduction in Transient Grating Spectroscopy

Transient grating (TG) spectroscopy is an important experimental technique to measure mean free path (MFP) spectra using observations of quasiballistic heat conduction. To obtain MFP spectra, the measurements must be interpreted within the framework of the frequency-dependent Boltzmann transport equation (BTE), but previous solutions have restricted validity due to simplifying assumptions. Here...
