Understanding thermal transport and temperature distribution within biological organs is important for therapeutic aspects related to hyperthermia treatments such as radiofrequency ablation (RFA). Unlike surface heating, the RFA treatment volumetrically heats up the biological media using a heating probe which provides the input energy. In this situation, the shape of the affected region is ann...
A micromechanics based thermal model was developed to predict the temperature and degree of cure (DOC) distribution inside a unidirectional fiber reinforced composite during the curing process. Using the concentric cylinder assemblage (CCA) model as a representation of the composite microstructure, the effective thermodynamic properties of the composite were computed based on the fiber and matr...
Abstract We study the long-term thermal evolution of axisymmetric rotating neutron stars in full general relativity. To this aim, we develop NSCool 2D Rot , a major upgrade to 1D code by Page. As first application our new code, address standard cooling isolated with rotation frequencies up mass shedding limit. investigate effects equation state (EOS) considering different combinations core and ...
In order to study the possibility of aerodynamic optimization base cavity for slender body, influence with non-cylindrical shape, which is different from traditional column one, investegated by numerical method in paper. The supersonic flow field same body two sorts unconventional cavity, half truncated-cone and column, simulated axisymmetric Navier-Stokes equations. Distribution Mach Number (M...
Composting experiments with heat recovery reveal spatial non-uniformity in parameters such as temperature, oxygen concentration and substrate degradation. In order to recover from static compost piles via integrated exchanger there is the need investigate temperature distribution for placing exchangers interaction between recovery, degradation ensure quality of composting process. This study in...
The spatial organization and time dependence of Jupiter's temperatures near 250-millibar pressure were measured through a jovian year by imaging thermal emission at 18 micrometers. The temperature field is influenced by seasonal radiative forcing, and its banded organization is closely correlated with the visible cloud field. Evidence was found for a quasi-periodic oscillation of temperatures i...
Preliminary results obtained by a code aimed to the analysis of three-dimensional (3D) instability of axisymmetric melt flows in Czochralski crucible are described. The CPU time and the computer memory necessary for the comprehensive 3D stability analysis by a second-order finite volume method are estimated. Basing on a certain experimental configuration, we give an example of the stability dia...
A d-dimensional spacetime is “axisymmetric” if it possesses an SO(d−2) isometry group whose orbits are (d−3)-spheres. In this paper, algebraically special, axisymmetric solutions of the higher dimensional vacuum Einstein equation (with cosmological constant) are investigated. Necessary and sufficient conditions for static axisymmetric solutions to belong to different algebraic classes are prese...
This article presents an exact solution for an axisymmetric functionally graded piezoelectric (FGP) rotating disk with constant thickness subjected to an electric field and thermal gradient. All mechanical, thermal and piezoelectric properties except for Poisson’s ratio are taken in the form of power functions in radial direction. After solving the heat transfer equation, first a symmetric dist...
