Electrical Modification of Combustion and the Affect of Electrode Geometry on the Field Produced

Modelling and Simulation in Engineering, 2011
There has been extensive work to show how electric fields can influence combustion. However, many different set ups are used. This work shows how different set ups produce different field strengths and that the field is not always uniformly distributed ...

Proračun transformatora u programskom paketu Ansys-Maxwell

, 2016
U diplomskom radu pokušalo se pokazati kako napraviti električni stroj, u ovom slučaju transformator u Ansoft Maxwell programu. Prvih nekoliko poglavlja su teorijska i opisuju transformator, njegovu ulogu i njegove nedostatke. Nakon toga, govori se o Maxwellu, kako i na kojim fizikalnim temeljima je nastao.
