GasTurbnLab Project
OVERVIEW
This project will develop technology and software systems for a
problem solving environment to analyze gas turbine dynamics. These
engines are very complex (with ~30,000 parts) and have extreme
operating conditions (with 10-50,000 RPM, 1000-1500 degrees F
temperatures, pressures of 20-50 atmospheres, and 5-10g loads). The
important physical phenomena take place on scales from 10-100
microns to meters. A complete and accurate dynamic simulation of an
entire engine is enormously demanding; it is unlikely that the
required computing power, simulation technology or software systems
will be available before 2010.
The primary research goal is to advance the state-of-the-art in very complex scientific simulations and to obtain better insight into the behavior of gas turbines. The major challenge is to integrate the science, engineering, and computation and then demonstrate that the results are reliable. The project's principal theme is to develop the GasTurbnLab problem solving environment (PSE) and its secondary theme is to validate this technology for gas turbine dynamics. These themes interact strongly with each other. Eight specific task areas are involved:
Problem Solving Environments
- Component-Based Simulation for Multidisciplinary Applications.
- GasTurbnLab: A Multidisciplinary Problem Solving Environment.
- Agent Based, Netcentric Collaborative Simulation.
Simulation Reliability and Validation
- Validation by Experiments and Physical Models.
- Validation of the Computing Environments.
Gas Turbine Engine Dynamics Analysis
- High-Cycle Fatigue and Life Analysis of Blade Rows.
- Simulation of Coupled Fluids, Structures and Combustion.
- Combustion and Pollutant Formation.
These strongly involve the disciplines of problem solving environments, computational science, computer systems, fluid dynamics, combustion, and structural dynamics. The overall project involves researchers from Computer Sciences and Mechanical Engineering.
