Deliverables

• A) A PSE research activity based on a turbulent flow, combustion and mechanical coupling in gas turbines as the driving application. Subtasks here include:

  A1: Simulate turbine rotors structurally and aerodynamically including misturning effects.
  A2: Simulate the combustor processes including atomization, spray, turbulence and combustion.
  A3: Simulate instability onset using the coupling of the rotors, compressor and combustor.

• B) Development of agent based collaborative simulation. Subtasks here include:

  B1: Develop a component based network model of the compressor, combustor and turbine of a gas turbine engine.
  B2: Develop an agent based PDE solving technique for multi-physics simulations.

• C) Development of a validation methodology that is integrated into the PSE. Subtasks here include:

  C1: Create a mechanism for direct comparisons of computed solutions with physical data, analytical solutions and physical models.
  C2: Develop an experimental design technique to assess the validity of a simulation program based on comparisons for individual solutions.

• D) Study of computational methodology for handling disparate scales in computation for gas turbines. The specific areas involved are linking micro-scale and macro-scale phenomena in 1)combustion and 2)turbine blade wear and performanace. Subtasks here include:

  D1: Linking micro-scale droplet formation and evaporation in combustion to macro-scale performance.
  D2: Linking micro-scale fatigue and wear of turbine blades to macro-scale performance.
