Solutions
Predict fluid and thermal behavior of cryogenic systems with GT-SUITE's two-phase flow solution, powered by a comprehensive NIST fluid properties database.
Solution Overview
Cryogenic systems are at the heart of spacecraft propulsion, and the reliable performance of these systems is critical to a successful space mission. GT-SUITE predicts the fluid and thermal behavior of these systems using a state of the art two phase flow solution powered by a large database of fluid properties provided by NIST, including common cryogenic fluids for space applications such as hydrogen, oxygen, methane, helium, nitrogen and more. Standard components like heat exchangers, valves, pumps, compressors, tanks, pipes, and volumes are included. When CAD data is available of the flow system, GT-SUITE’s pre-processor, GEM3D, discretizes the flow system and models heat transfer from the flow passages to the surrounding structure.
Analyze steady state operating points or transients ranging from water hammer to thermal loading over a flight mission. Built-in optimization and DOE tools allow component sizing, system layout, and optimization of control strategies. Beyond thermal and fluid analysis, GT-SUITE supplies complete component libraries which simulate the physics of mechanical, electrical, magnetic, chemistry, and controls components as well.
Application Highlights
GT-SUITE goes beyond fluid and thermal analysis with built-in tools for optimization, co-simulation, and multi-physics integration
Integrate GT-SUITE with TAITherm to apply full 3D radiation, conduction, and convection boundary conditions directly to cryogenic system models . Study how radiation loading in space affects fluid and thermal behavior across complete mission profiles.
Connect GT-SUITE with virtually any commercial or in-house software tool to extend your simulation environment without constraint . Preserve existing workflows and toolchains while gaining access to GT-SUITE's cryogenic fluid and thermal physics.
Run DOE studies and optimization routines natively within GT-SUITE, from individual component sizing to full system energy consumption . Eliminate the need for external optimization frameworks and accelerate design decisions at every stage.
Predict the fluid and thermal behavior of cryogenic systems using a state-of-the-art two-phase flow solver backed by NIST-validated fluid property data. Supported fluids include hydrogen, oxygen, methane, helium, nitrogen, and more, covering the full range of common space propulsion applications.
Convert 3D CAD geometry of cryogenic flow systems directly into 1D simulation models using GT-SUITE's GEM3D pre-processor . Heat transfer between flow passages and surrounding structure is preserved automatically, reducing model build time significantly.
Analyze cryogenic system performance across the complete operational envelope, from steady-state operating points through demanding transients including water hammer events and full flight mission thermal loading, within a single modeling environment. Standard components including heat exchangers, valves, pumps, tanks, and pipes are included out of the box.
GT-SUITE includes a comprehensive fluid property database sourced from NIST, covering hydrogen, oxygen, methane, helium, nitrogen, and other fluids commonly used in space applications . This means you can model real-world propellant behavior accurately without building custom fluid libraries from scratch.
Yes. The solver is specifically designed to remain stable and accurate even when fluid transitions between liquid and vapor phases, a common challenge in cryogenic propulsion systems. The energy equation is always solved, and the solution handles dynamic control scenarios without sacrificing numerical stability.
GT-SUITE supports co-simulation with TAITherm (RadTherm), which provides 3D radiation thermal boundaries directly to the GT-SUITE model . This allows engineers to evaluate cryogenic system performance under realistic space radiation loading conditions, not just ground-level assumptions.
Component sizing, system layout studies, and control strategy optimization are all supported through GT-SUITE’s built-in DOE and optimization tools . Engineers can run parametric studies across heat exchangers, valves, pumps, tanks, and piping to arrive at an optimized design before hardware is ever built.
