The nozzle performance was considered in the present work.
Multi-linear regression was used to correlate the nozzle performance to various nozzle parameters.
The intensity of the current flowing through the electrode was, therefore, used to define a spray nozzle performance index.
In this paper the performance of Coanda-type nozzles is examined in detail and an index rating for nozzle performance is introduced.
Finally, we demonstrate the method with a more complex application problem, and discuss results of simulation for a quasi bi-dimensional self-field magnetoplasmadynamic (MPD) thruster, for which we study the effect of cathode length upon the electromagnetic nozzle performance.
Calculations of nozzle performance and wall pressures were made using computational fluid dynamics analyses with and without thrust augmentation flow, resulting in good agreement between calculated and measured quantities including augmentation thrust.
