GT-SUITE Waste Heat Recovery (Rankine Cycle) Modeling

This 1-day training course is designed to introduce the modeling of Rankine Cycle based Waste Heat Recovery Systems in GT-SUITE. It is designed for users who have had a basic introduction to GT-SUITE, that are interested in modeling such systems, with the end goal of integration with a GT-POWER engine model.

Each student will be provided with a computer. The course will include the construction of models and use of the software, which will enable the participants to use the software immediately. It will cover the following topics:

1. Modeling Waste Heat Recovery Systems:

   • Introductory Concepts of GT-SUITE
   • Overview of modeling various Waste Heat Recovery System concepts in GT-SUITE
   • 1-D Flow Simulation and 2-phase Flow Modeling
   • Review
   • Model Setup- initialization, parameters sweeps, convergence
   • Post-processing (GT-POST)
   • Subassemblies

2. Modeling Rankine Cycles:

   • Major components (pipes, pumps, turbines, heat exchangers etc.)
   • Building and calibrating each component to experimental data
   • Assembling components of a basic Waste Heat Recovery System
   • Performing steady state and transient analysis
   • Incorporation of thermal management control strategies

3. Integration of Waste Heat Recovery System with a GT-POWER engine model:

   • Integrate Waste Heat Recovery System into EGR cooling circuit of GT-POWER engine model

Underhood Simulation: If time permits at the end of the class, the instructor will introduce a quasi-3D underhood flow model using the CAD-based preprocessing tool, COOL-3D. This tool allows for the solution of the transient air flow around and/or through grilles, blockages, stacked heat exchangers, fans, and the engine block. This tool can be used for example to scale heat exchanger size. It can be used to model the heat exchanger used to cool the Rankine Cycle Condenser (Condenser Cooler).
