Simulating Flow & Heat in Gas Turbine Engines

Description: 

Whether gas turbine (GT) engines are used for aircraft propulsion or for ground-based power generation, they involve sophisticated subsystems that ‘turn’ (compressors and turbines) and ‘burn’ (combustors). The goal with GT engines is to provide the rated power with maximum fuel efficiency and uptime reliability, while not exceeding government-regulated levels of emissions. 

While separately each GT subsystem must be designed for maximum performance, together they must also be designed to work harmoniously to ensure the entire GT engine system functions as intended. 

Trying to find an optimal balance between these competing objectives and constraints is a task very well-suited to CFD simulation and automated design space exploration.

In this educational webcast, the 1st of a 3-part series, presenters share several case studies where STAR-CCM+ was used to show the advantages of simulating GT engines:  

  • Meshing complex geometry such as combustor liners and turbomachinery blades, having numerous cooling holes with little-or-no need to manually repair auto-mesh results
  • Rapidly exploring design options that can optimize performance while avoiding potentially damaging pressure drops and thermal failures
  • Combining aerodynamics (flow) and thermal calculations as part of conjugate heat transfer (CHT) simulations, all in one environment
  • Conveying boundary conditions from one subsystem of the GT engine onto another, accurately and automatically
  • Gaining deeper insight into transient turbomachinery behavior through simulations involving our computationally efficient Harmonic Balance Method

Within the series, experts employ STAR-CCM+ to go even deeper into the technical details associated with how gas turbine subsystems that turn and burn can be simulated more accurately and efficiently.
