A parametric macro model for a single and dual conductor power cable for transient thermo-electrical coupled simulation in PSPICE will be derived. The articledepicts the modelling of a simplified, singleand dual conductor cable and its use during simulation. Its verification against experiment and finite element simulation shows a good agreement. The derived singleand dual conductor PSPICE cabl...

Building energy model reduction exchanges accuracy for improved simulation speed by reducing the number of dynamical equations. Parallel computing aims to improve simulation times without loss of accuracy but is poorly utilized by contemporary simulators and is inherently limited by inter-processor communication. This paper bridges these disparate techniques to implement efficient parallel buil...

ABSTRACT Monte Carlo (MC) simulation has been abundantly used for simulation of radiation transport (thermal, neutron, charged-particle etc) in matter. In thermal radiation, for example, surface radiosities and subsequent heat fluxes have been accurately determined in configurations which are difficult for deterministic formulations. In this paper, we consider estimation of the collision densit...

Thermal resistance is a key technical index which indicates the thermal management of multi-chip module high power LED (MCM-LED) packaging heat dissipation system. In this paper, the prototype structure of MCM-LED packaging heat dissipation system is proposed to study the reliable thermal resistance calculation method. In order to analyze the total thermal resistance of the MCM-LED packaging he...

Nonpenetrative convection Ð in which the lower boundary condition is one of constant heat flux and the upper boundary is insulatedÐ is an idealization of penetrative convection, which finds application in the planetary boundary layer. Three-dimensional, unsteady, ( ) direct numerical simulations 96 = 96 = 128 have been performed of turbulent, nonpene7 trative thermal convection inside a cubical...

Soil emissivity signatures were constructed using the digital imaging and remote sensing image generation (DIRSIG) model and Blender three-dimensional (3-D) graphic design software. Using these tools, the geometry, radiometry, and chemistry of quartz were exploited to model the presence of particle size effects in the thermal spectra of disturbed soil. Using the physics engines within the Blend...

We present a program package based on finite elements for twoand three-dimensional analysis of interconnect structures. Thereby, triangular and tetrahedral grid elements with quadratic shape functions are used. Two preprocessors allow a layer-based input of the simulation geometry and the specification of the boundary conditions. The main program calculates amongst other things the distribution...

This paper considers the design and optimization of thermal systems on the basis of the mathematical and numerical modeling of the system. Many complexities are often encountered in practical thermal processes and systems, making the modeling challenging and involved. These include property variations, complicated regions, combined transport mechanisms, chemical reactions, and intricate boundar...
