Thermal Modeling of Phoenix Cubesat

by Johnathan Gamaunt, Arizona State University 

The Phoenix CubeSat is an undergraduate-led 3u CubeSat designed to study Urban Heat Islands through infrared imaging.   The Phoenix mission is an educational mission, where our primary goal is to develop a functioning CubSat, capable of imaging the Earth in the IR spectrum.  The data collected form the mission will support the study of how city composition, using local climate zones, affects the surface Urban Heat Island signature in major U.S. cities. 

The success of this mission depends on maintaining all components within their operating temperatures for component survival, and keeping the camera thermally stable in a specific temperature range to get usable science data.  Thermal Desktop gave us an analysis environment to make these temperature predictions and solve complex thermal models.  Thermal Desktop has a simple feel about it that allows you to build and customize your design in an intuitive way.  Using the Logic Manager, I was able to model all of the satellite rotations in orbit for imaging.  I was also able to model all of our TVAC tests and correlating real data to the thermal model to fine tune the real flight predicts. 

Thanks to C&R Technology for providing the Phoenix CubeSat program access to this software; because of this experience I was able to obtain an internship at NASA’s Jet Propulsion Laboratory where I was able to future develop my Thermal Desktop skills.

Introduction to Two-phase Flow

September 24, 2-3pm MDT

This webinar introduces basic concepts in two-phase flow modeling including quality, void fraction, flow regimes, slip flow, pressure drops and accelerations, and heat transfer.

No knowledge of CRTech software is required. However, references to the corresponding FloCAD features will be made to assist users of that product.

Introductory FloCAD Training

Class times: September 5, 10, and 12, 2019, 9:00 am to 12:00 pm MDT daily
Cost: no charge (attendees must have an active support contract)

CRTech will be hosting introductory training for FloCAD (Flow Modeling in Thermal Desktop). This is our standard FloCAD class previously hosted in a classroom environment and now restructured for an online teaching environment.

The class will introduce single-phase fluid modeling concepts and how to build fluid models within the FloCAD work environment. Topics covered include an introduction to fluid modeling components, geometric versus non-geometric modeling options, working with FloCAD Pipes, solution control, and an introduction to path and pipe libraries.

The class will be broken into three two- to three-hour sessions held over a 3 day period. The format will be online lecture and demonstration with opportunities to ask questions. Hands-on lab work will be provided to students to work on after each session. To gain the most from this class, students are encouraged to attend all three sessions.

Prerequisites: Attendees must have basic working knowledge of Thermal Desktop as many of its base features will not be covered in this class but their usage is required for FloCAD.

Eligibility Requirement: This class is a service to our customers. All attendees must have an active support contract. If you are unsure of your support status, please contact CRTech.
