High-fidelity simulation of ablating Thermal Protection Systems (TPS) mounted on an airframe in realistic high-enthalpy environments
Video Recording
Presented By Bruce Crawford
One of the key technical challenges for hypersonic vehicles is the protection of the airframe and of the propulsion system from the high and sustained heat fluxes encountered during atmospheric re-entry flight and, to a lesser extent, during hypersonic cruise. Several engineering solutions have been used over the years to cope with the high heat fluxes, including active and passive cooling and ablative protection systems.
Ablating Thermal Protection Systems (TPS) have been the most prevalent solution to protect those areas on the airframe with the highest heat fluxes, such as vehicle noses, leading edges, engine inlet cowls, and for re-entry systems, the blunt end of the vehicle. However, the design of TPS systems is a challenging endeavor given the difficulty in generating accurate and reliable experimental data.
Because of the almost impossibility of reproducing realistic flow conditions in a ground-based testing facility, and because of the extreme costs and difficult data reduction associated with flight experiments, computer simulations become a key enabling technology in the design of communication systems for re-entry vehicles. Once validated, high-fidelity computer simulations can reproduce accurately the physical phenomena and their complex interactions, thus reducing drastically the need for wind tunnel and flight testing.
In the present work, we are proposing an innovative Multiphysics workflow to address the high-fidelity modeling of realistic TPS geometries and materials embedded in a high-enthalpy environment, including the heat conduction effects into the airframe.
The ablating surface is modeled using an empirical and/or first principles models and methods, which include surface reactions, discrete particles, and conjugate heat transfer to name a few.
This framework includes the new panels to specify ablation dynamics, such as Vielle’s Law and/or with gas and surface reaction models, and an automatic workflow for the mesh deformation and motion (MDM).
Relevant generic case studies will be presented and a roadmap for future development will be discussed.

NASA MSFC Generalized Fluid System Simulation Program (GFSSP), Tuesday, 13:00-14:00
Presented By Alok Majumdar
GFSSP is a general-purpose computer program for analyzing steady-state and time-dependent flow rate, pressure, temperature, and concentrations in a flow network. The program can model phase change, subsonic compressibility, fluid mixtures, conjugate heat transfer, and external body forces. GFSSP was developed at the Marshall Space Flight Center for flow analysis of rocket engine turbopumps and propulsion systems.
A brief overview of GFSSP’s capabilities will be given. Then a demonstration will show how to construct a simple GFSSP model from scratch. Finally, existing models will be presented to showcase applications of GFSSP, including tank pressurization, turbopump secondary flow analysis, waterhammer, priming, and propellant transfer line chilldown.

Maya HTT (see times below)
Simcenter 3D Space Systems Thermal is a comprehensive space systems thermal modeling and simulation tool tightly coupled to the CAD geometry. The thermal environment in either outer space or on the surface of a planet or moon is fully defined when the user supplies basic parameters. Geometry can be as simple as a collection of primitives, or as detailed as a fully populated CAD assembly of a spacecraft or rover.

Thermal Software System
Presented By Joe Clay
Thermal Software System (TSS) is a thermal analysis tool to model spacecraft in the space thermal environment. The software converts CAD based models to a thermal engineer friendly format. Analysis can be performed to determine radiation conductors, conduction network, and produce temperatures within a 3D graphical environment. The software is built in C++, Microsoft .NET framework, and OpenGL. Spacedesign Sinda/Fluint is an numerical integrator for thermal and 2 phase fluid models used to solve for temperatures and fluid flow.
The presentation will discuss the enhancements in TSS v16 and more.

TAITherm Human Thermal Model
Video Recording
Presented By Timofey Golubev
The TAITherm Human Thermal Model (HTM) is a complex thermophysiological model that creates a thermal nodal network describing a human starting with a geometric description of the body. Each element is associated with tissue layers appropriate to the part of the body being represented. Metabolic heating, shivering, respiration, sweating, and peripheral vasomotion are the primary physiological responses modeled to simulate a human body as it attempts to maintain homeostasis. These responses are used to adjust the coefficients of the bio-heat transfer equation, which is solved to predict skin and core temperature response to rapidly changing and asymmetric environments. Additionally, the TAITherm HTM predicts the evaporation and condensation of moisture within clothing fabric layers that subsequently affect liquid content, temperature, and ultimately, thermophysiological response and thermal comfort perception. The TAITherm HTM interacts with a simulated thermal environment and provides a suite of temperature, heat flow, and thermal comfort metrics as output.
In this session, we will provide a brief overview of the TAITherm HTM’s capabilities. Then we will demonstrate how to setup a human model. Finally, we will present an example application where the HTM was applied to assessing crew-induced loads in spacecraft.
