The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simultaneously using transient plane source technique. The temperature dependence of thermal transport properties is studied in the temperature range 83-303 K. Different relations for the estimation of thermal conductivity are also tested. T...

in this paper, wavelet collocation method has been used to solve nonlinear fin problem with temperature dependent thermal conductivity and heat transfer coefficient. thermal conductivity of fin materials varies any type so that we consider thermal conductivity as the general function of temperature.  here we consider three particular cases, where we assume that thermal conductivity is constant,...

In the present Rapid Communication we present an analytical and numerical solution of the self-consistent mode-coupling equations for the problem of heat conductivity in one-dimensional systems. Such a solution leads us to propose a different scenario to accommodate the known results obtained so far for this problem. More precisely, we conjecture that the universality class is determined by the...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

application of feed pellets in animal and aquatic farming industries has grown because of both the physical and the nutritional benefits it provides. development of feed pellets manufacturing industry is also considerable. steam conditioning process, which plays an important role in pelleting production, includes heating feed particles, adding moisture, and mixing the mash. pellets cooling and ...

Anomalous large thermal conductivity has been observed numerically and experimentally in one- and two-dimensional systems. There is an open debate about the role of conservation of momentum. We introduce a model whose thermal conductivity diverges in dimensions 1 and 2 if momentum is conserved, while it remains finite in dimension d > or = 3. We consider a system of harmonic oscillators perturb...
