Radiation Transfer Modeling in Electrothermal Chemical (ETC) Ignition
Abstract
The use of plasma ignition for high-performance guns has been pursued at several levels. As part of the program at the U.S. Army Research Laboratory (ARL), we are attempting to define the role of the broadband electromagnetic radiation that is a key energy component of the plasma discharge. In particular, this effort is developing a radiation transfer model that will be incorporated into the computational fluid dynamics (CFD) model of plasma ignition This effort will allow more physically realistic characterization of the energy transfer in the plasma and its interaction with the propellant in the models. This report summarizes the physical background of the radiation transport, and the validation of the different submodules by use of published data will be presented. Current efforts include the coupling of the radiation model to the ARL NSRG2 code for the plasma-propellant interaction simulation. Furthermore, a series of laboratory experiments will be performed to validate the CFD code with the incorporated radiation transport submodel.
