Integrated Systems Modeling
Mass and energy transport through simple or complex systems is modeled using proprietary software tools developed and applied by Paragon to a wide range of life support applications. The emphasis is on development of useful models that inform the design of systems we develop for our customers.

Computational Fluid Dynamics
Paragon’s CFD specialists tackle a wide range of flow problems as encountered in human spaceflight. Examples include air flow and mixing in crew cabin ventilation, flow through air revitalization systems, flows with multiphases, multispecies, chemical reactions, and phase changes, flow in turbomachinery, subsonic, transonic, supersonic, and hypersonic aerodynamics, aerothermodynamics, fluid-structure interactions, etc.

Human Thermal Modeling
Paragon’s 3-D human thermal analysis tool integrates our human thermoregulatory system model into the Thermal Desktop analysis platform to provide the capability to model crew member, suit geometry, life support hardware/geometry, vehicles or environment into one complete system model.
