Abstract:
An Interactive Tool for Discrete, Phase Analysis in Two-Phase Flows
Multi-phase flow effects in liquid and solid propulsion systems have profound implications
on performance and durability. For example, the dynamics of a aluminum oxide particulates
in solid rocket motor affects the slag accumulation, thereby affecting the performance.
Particulate impingement on the motor casing and nozzle affects the durability via
its influence on the thermal load on the insulator. The effect of the discrete phase
on performance and durability can be significant even when the concentration of the
discrete phase is too low to alter the continuous-phase flow-field in a significant
manner. An innovative workstation-based analysis tool that can be used by analysts
and designers to assess the discrete phase effects during the development and testing
of rocket propulsion systems will be developed. The workstation-based software will
use Lagrangian analysis for the discrete-phase motion and will include a graphical
interface allowing the user to change the relevant parameters to conduct parametric
studies interactively.
The analysis of discrete phase effects applies to a variety of applications that
involve two-phase flows, for example liquid and solid rocket propulsion systems,
sand/particle separators, and fans and compressors operating in a dusty environment.
