Waste Heat Recovery Simulation

Mature, robust waste heat recovery system modeling

Waste Heat Recovery INTEGRATED SIMULATION FOR RECOVERY SYSTEMS

Various technologies are being explored to make use of the hot exhaust gases from engines Two of these technologies that can be modeled in GT-SUITE are Rankine cycle and TEG (Thermo Electric Generator) systems.  These systems can be integrated with a GT-POWER engine model to predict energy recovery across a wide range of operating conditions. 

Using GT-SUITE’s proven two-phase approach used in modeling air conditioning systems with fluid properties from NIST Refprop, Rankine cycle models are simulated to explore fuel savings and investigate advanced control strategies.  Complex layouts including multiple heat exchanger stages and valving systems are supported. 

Studies using TEGs include investigating new advanced Peltier-effect materials and different layouts for maximizing the amount of power generation between the hot and cold streams. Companies using GT-SUITE can reduce physical testing by finding optimal designs in simulation instead of trail-and-error testing. 

Waste Heat Recovery APPLICATION HIGHLIGHTS

  • Model all Rankine/TEG system components individually or as a complete system
  • Fluid properties calculated from built-in NIST REFPROP
  • Spatially resolved condenser and evaporator models to capture phase change
  • Automatic calibration of all components – heat exchangers, expander, etc
  • Robust solver based on Navier-Stokes equations allows arbitrary initial state and zero flow
  • Fast simulation (faster than real-time)

Advanced Features

  • Investigate advanced controls strategies for optimizing power output
  • Integrate with existing GT-POWER engine model to study engine-WHR system interaction
  • Use proprietary supplier-generated NIST Refprop FLD and MIX files – all supported automatically
  • Predict heat exchanger performance when geometry is changed (scaled)
  • Optimize system layout for different configurations
