Two fluid model for cold, low-pressure hydrogen plasma

The present Master of Science thesis, deals with the development of a 0-D, steady-state model for cold Hydrogen plasma, in the pressure limits of 10-60 Torr. This code, is the first step for the development of a general code which could face a great range of plasmas (apart from Hydrogen plasma), co...

description The present Master of Science thesis, deals with the development of a 0-D, steady-state model for cold Hydrogen plasma, in the pressure limits of 10-60 Torr.
