ADVANCES IN 3D ELECTROMAGNETIC FINITE ELEMENT MODELING
Numerous advances in electromagnetic finite element analysis (FEA) have been made in recent years. The maturity of frequency domain and eigenmode calculations, and the growth of time domain applications is briefly reviewed. A high accuracy 3D electromagnetic finite element field solver employing quadratic hexahedral elements and quadratic mixed-order one-form basis functions will also be described. [...]
Loading ...Analysis of Electromagnetic Field Effects Using FEM for Transmission Lines Transposition
This paper presents the mathematical model of electric field and magnetic field in transmission system, which performs in second-order partial differential equation. This research has conducted analyzing the electromagnetic field radiating to atmosphere around the transmission line, when there is the transmission line transposition in case of long distance distribution. The six types of 500 [...]
Finite Element Electromagnetic Analysis of TWT Electron Guns in Grid Environment
In this paper some new Finite Element procedures are presented to analyze TWT electron guns in the GRID environment. In particular very computing time expensive analysis required in TWT electron guns simulations are parallelized in order to obtain a remarkable reduction of computing time. The example presented regards the construction of the current-voltage relationship for [...]
CFD ANALYSIS OF CONVECTIVE HEAT TRANSFER COEFFICIENTS ON THE EXTERIOR SURFACES OF A CUBIC BUILDING
The forced convective heat transfer at the surfaces of a cubic building in an atmospheric boundary layer is investigated with CFD. Heat transfer in the boundary layer is modelled using low-Reynolds number modelling (LRNM) and standard wall functions (SWFs). SWFs are found to overestimate the convective heat transfer coefficient (CHTC) significantly. Using a customised wall [...]
