TFAWS 2016 session content encompasses paper sessions, instructor-led short courses, hands-on software training, and vendor demonstrations to further advance the thermal-fluids aerospace community.
Paper sessions provide the opportunity for those in the thermal-fluids community to present their work to their peers. This allows for greater dissemination of this material within the community as well as provides a valuable forum for discussion about its applicability to other advancements within the various disciplines. The paper sessions are split into five categories based on the general focus for each topic area: Active Thermal, Passive Thermal, Heat Pipes, Aerothermal, and Interdisciplinary.

Advanced TSS including v15.01B and CAD Transfer
Tuesday, August 2, 8:00am – 5:00pm, Room 105/106
Instructor: Joe Lepore, Joe Clay (SpaceDesign)
This hands-on class will demonstrate more TSS features and modeling techniques. Topics will include: Radiation analysis of CAD surfaces using STEP and IGES Translators, SindaWin application and using LDDATA to automatically record local minimum and maximum temperatures, Geometry model validation, building models with Symbols, distributed processing, managing Boolean surfaces and chains, adjusting conductor values, using the Mesh and FEM applications, and SATSTRAN. Topics of specific interest to users and v15 enhancements will be discussed. Example topics include the rich feature set in TSS such as programming in the command language, utilizing TSS as a prototyping tool, eliminating costly 3rd party applications to move data from a CAD package to a thermal software system, and utilizing TSS as a simple CAD package.
The Transfer application is used to view CAD models and transfer them into TSS geometry format. Transfer has a ‘CAD viewer’ built-in, allowing you to view any CAD model saved in IGES, STEP, or OBJ format. This viewer shows a meshed representation of the model which can then be transferred to TSS Geometry format in a single step. Using advanced 2-D and 3-D Boolean capabilities (computational geometry), complex CAD entities are converted into thermal surfaces using fewer surfaces for radiation analysis. Transfer methods available include direct conversion to files compatible with specific TSS versions, plus a 2-D mesh approximation using surfaces or boundary representation.

Thermal Analysis Results Processor (TARP) and COVeR: Capture Output and Verify Results
Wednesday, August 3, 8:00am – 5:00pm, Room 105/106
Instructor: Hume Peabody
Hume Peabody graduated from Virginia Tech with a BS in Mechanical Engineering in 1994 and an MS in 1997. Outside of his normal 9-5 day job, Hume founded Thermal Modeling Solutions, LLC in 2005 and released the first version of TARP in 2007, a program dedicated to creating post-processing products from standard thermal solver outputs. Since then, steady improvements and feature additions have been made to increase the types of products available.
The first half of the course will introduce the basic object types in TARP, including: DataSets, Groups, Parameters, Plots, Tables, and HeatMaps. More advanced data objects will also be discussed including: Backloads/Equivalent Sinks, Graphical Tables, Radk Compares and Manipulations, and Binary Heat Maps. The second half of the course will focus on the COVeR environment, including: Data Selection, Groups, Plotting, and Graphical HeatMaps, which are a block diagram way of visualizing heat flow data from model output.
Thermal Modeling Solutions was founded in 2005 by Hume Peabody. The first product TARP (Thermal Analysis Results Processor) was a dedicated post processing environment for interfacing with Microsoft Excel and standard output files from many commercial thermal solvers. Future releases featured additional capabilities for visualizing data and addressing ever growing model sizes. More recently, the COVeR (Capture Output and Verify Results) tool was released, which provides a self contained environment for the processing of model output, with a specific focus on heat flows. The underlying philosophy in both TARP and COVeR is two-fold: be able to read output from many commercial, network based tools and nodal level results can
be grouped to represent physical components of a design. While models may be growing in size, the fundamental behavior of heat flow between components of a design remains unaffected by model size.

Siemens PLM NX Thermal, Flow, and Space Systems Thermal will be demonstrated by Carl Poplawsky with Maya Simulation Technologies. These add-on software modules provide heat transfer and fluid flow solutions when used with NX Advanced Simulation. NX Thermal simulates conduction, convection and radiation phenomena and NX Flow provides sophisticated tools to simulate fluid flow for complex parts and assemblies; when used concurrently they provide a fully coupled multi-physics solution. NX Space Systems Thermal is the NX space industry vertical application that provides a comprehensive set of tools to simulate orbital thermal analysis within the NX Advanced Simulation environment.
ThermoAnalytics Human Thermal Modeling Tutorial and Software Demo
Thursday, August 4, 1:00pm – 3:00pm, Room 117
Instructor: Al Curran
Dr. Curran is the Chief Technical Officer and co-founder of ThermoAnalytics, Inc. Dr. Curran’s current research focuses on the development of human thermal physiology and comfort models. His previous research formed the basis of Ford Motor Company’s thermal radiation analysis software, RadTherm, which evolved to become TAITherm. TAITherm is a general-purpose thermal simulation environment, which is in use worldwide, primarily in the automotive industry. Dr. Curran received his BS and MS in Mechanical Engineering from Northwestern University and his PhD in Mechanical Engineering from Stanford University.
ThermoAnalytics’ Human Thermal Module (HTM) is an advanced, off-the-shelf thermo-physiological model that plugs into the powerful heat transfer simulation software, TAITherm. The HTM simulates the process by which the body attempts to maintain a constant core temperature. Numerous commercial and government entities use ThermoAnalytics’ HTM. For example, NIOSH uses the HTM to predict skin and core temperatures as well as evaporation rates of mine shelter occupants. Additionally, MIT has used the TAITherm HTM to model its mechanical counter pressure (MCP) suit. In this session, we describe state-of-the-art “segmental” human thermal models and demonstrate the capabilities of the TAITherm Human Thermal Module.
ThermoAnalytics is a leading developer of thermal, fluid flow, and infrared modeling software. Located in Michigan’s Upper Peninsula, ThermoAnalytics has been developing the TAITherm thermal simulation software, which models the effects of radiation, conduction, convection, advection, evaporation/condensation, phase change, etc., for over 20 years. They provide software and engineering analysis for complex heat transfer problems. The TAITherm software is used to find solutions for a wide variety of thermal applications, including transient (automotive) brake heating; under-hood, exhaust and underbody heating; HVAC and cabin thermal comfort; battery pack heating for HEVs/EVs; and protecting electronics and other thermally sensitive components. This powerful software offers fast transient thermal analysis and couples to CFD and FEA software, which facilitates an efficient design optimization process. TAITherm finds its greatest use in the automotive, aerospace, heavy vehicle, and railway industries.
COMSOL Demo: Coupling Between Physics, Between Scale, and Between Solutions With COMSOL Multiphysics
Thursday, August 4, 3:00pm – 5:00pm, Room 117
Instructor: John Dunec, VP of Sales, NW U.S., COMSOL Inc.
COMSOL Multiphysics® makes it easy to link multiple physics together either as fully coupled (probably nonlinear) problems or to solve one physics based on the results of another. You can also link between dimension (say, simultaneously 2D and 3D) or between solutions. This demo is designed to show a variety of coupling techniques over a wide range of physics. One particular problem we will build and run involves a combination of thermal expansion due to microwave heating with surface currents, involving both structural shells and solids, with forced convective cooling using both convection coefficients and full CFD simulations. It is purposely designed to involve a large number of physics coupled in a variety of different ways. Those new to COMSOL will see how easy it is to set up and solve models in COMSOL, those more experienced will see advanced methods to link between physics and link between solutions. COMSOL Multiphysics® is a general-purpose analysis platform, based on advanced numerical methods, for modeling and simulating a wide range of single-physics or coupled-multiphysics phenomena.
