Advanced Controls Optimization
Develop and validate control strategies that maximize energy recovery across all engine operating conditions. Simulation-driven development cuts calibration time and speeds deployment of production-ready systems.
Turn waste heat into usable energy. Model ORC and TEG systems for any heat source.
SOLUTION OVERVIEW
From Any Heat Source to Usable Energy
Large amounts of thermal energy are rejected every day by industrial processes, data center cooling systems, and combustion engines. Organic Rankine Cycle (ORC) and thermoelectric generator (TEG) systems can recover part of that energy as electricity or useful heat, but their performance depends strongly on heat source temperature, transient behavior, working fluid, and controls.
GT-SUITE enables engineers to estimate the energy recovery potential by modelling ORC systems at the component and system level, using a proven two-phase solution and NIST REFPROP fluid properties. The same models linked to a GT-POWER engine model, an industrial process model, or other thermal model predict recovered power, efficiency, and net system benefit across the full operating range including dynamic operation.
Whether for an industrial process or a container ship marine engine, GT-SUITE lets you get the most out of the system.

ADVANCED FEATURES
Comprehensive Waste Heat Recovery Modeling
Model, analyze, and optimize waste heat recovery systems with advanced simulation tools that capture component behavior, system interactions, and real-world operating conditions.
Seamless GT-POWER Engine Integration
Connect WHR models directly to existing GT-POWER engine circuits to capture full engine and recovery system interaction. Predict fuel savings and system-level performance accurately, without rebuilding models from scratch.
Geometry-Based Heat Exchanger Scaling
Quantify how heat exchanger geometry changes, including scaling for different system sizes, affect performance without new test data. Supports rapid design iteration and early component selection.
Reliable Results, Every Stage
GT-SUITE models the full recovery cycle in detail, capturing how the working fluid heats, vaporizes, and cools through the system. From quick concept studies to detailed performance checks, results reflect real-world behavior and give you confidence before hardware is built.
Multi-Configuration System Layout Optimization
Evaluate and compare WHR system architectures, including complex layouts with multiple heat exchanger stages and valving, to identify the best-performing configuration for your application. Find optimal designs in simulation and reduce costly physical prototyping.
Any Fluid, Ready Instantly
GT-SUITE supports a wide range of refrigerants and working fluids out of the box, and accepts custom supplier fluid data files automatically, with no conversion or setup required. Work with the exact fluids your system uses from day one.
