MEASUREMENT OF FLUID PROPERTIES FOR MAGNETOPLASMADYNAMIC POWER GENERATORS
Abstract
The objective of this program is to obtain basic information on the plasma properties of working fluids for magnetplasmadynamic (MPD) power generators. This information will be obtained through the use of diagnostic methods with em phasis on advanced spectroscopic techniques. The experimental approach of the program con centrates on a plasma loop through which helium seeded with cesium circulates through the test section at a variable temperature range of 1000 to 2000 degrees K. The flow rate of the atmos pheric pressure helium is varied between 7 to 12 gm/sec to achieve a Mach number of 0.9 through an area of approximately 1.2 square cm. Designed specifically for diagnostic investigation, the test section employs the basic features common to MPD generators. In preparation for the oper ation of the plasma loop, experimental effort has been applied to the development of new spectro scopic techniques and methods of evaluating observed spectra. Investigations will be made on the efficiency of various nonthermal ionization techniques. The theoretical approach consists of developing a theoretical model to describe non equilibrium plasmas and supplementary theoretical analyses to aid in design of improved MPD power generators. Instabilities occurring in the plasma flow will be investigated.
