Thermal properties (diffusivity and heat capacity) at varying temperatures up to 200°C and the thermal diffusivity under hydrostatic pressures up to 1 GPa at room temperature were measured on two basaltic samples recovered from Hole 504B drilled during Ocean Drilling Program Leg 148. Rock fabrics and porosity are key factors controlling the thermal properties of these rock samples. Estimates of...

Article history: Received: 13.4.2016. Received in revised form: 4.1.2017. Accepted: 12.1.2017. This paper presents a part of a computer model that is suitable for limited temperature prediction and its application for Lake Botonega, which is located in Istria, Croatia. The main assumption of this study is that the heat transfer can be described by the eddy diffusivity model to formulate the mod...

The heat capacity of supercooled water, measured down to -37°C, shows an anomalous increase as temperature decreases. The thermal diffusivity, i.e., the ratio of the thermal conductivity and the heat capacity per unit volume, shows a decrease. These anomalies may be associated with a hypothesized liquid-liquid critical point in supercooled water below the line of homogeneous nucleation. However...

A data reduction method based on numerical solutions of the heat conduction equation has been developed for obtaining thermal diffusivity values from thermal flash measurements. Using the new method, the computed evolution in temperature is fitted to the measured temperature evolution instead of using the t1/2 point alone, as is done in many other analyzes. The numerical solutions used are base...

Knowledge of mechanical and physical property evolution due to irradiation damage is essential for the development of future fission and fusion reactors. Ion-irradiation provides an excellent proxy for studying irradiation damage, allowing high damage doses without sample activation. Limited ion-penetration-depth means that only few-micron-thick damaged layers are produced. Substantial effort h...

Most conventional Raman thermometry for thermal properties measurement is on steady-state basis, which utilizes either Joule heating effect or two lasers configurations coupled with increased complexity of system or measurement uncertainty. In this work, a new comprehensive approach including both transient and steady-state Raman method is proposed for thermal properties measurement of micro/ n...

In this paper we have estimated typical anomalous viscosity, resistivity, and thermal difffusivity of the solar wind plasma. Since the solar wind is collsionless plasma, we have assumed that the dissipation in the solar wind occurs at proton gyro radius through wave-particle interactions. Using this dissipation length-scale and the dissipation rates calculated using MHD turbulence phenomenology...

The subject deals with a reduced model of the conductiveradiative transient transfer in a participating medium. The accuracy of the analytical solution based on the well-known two-flux approximation and expressed with global radiative coefficients is tested in the case of sharp thermal excitation by a heat pulse on the front face of anisotropically scattering media. A very good agreement is ach...
