Shadow Tracking

Using RadCAD® for Shadow Tracking

Using the Monte Carlo ray tracing capabilities in RadCAD, Olivier Godard and Tejas Shah came up with this visual simulation of tracking the shadow of the International Space Station (ISS) on the belly of the Space Shuttle. The Shuttle is oriented with the payload bay doors looking nadir (facing earth) while the ISS, traveling at the same speed at a slightly higher altitude, passes over the belly of the shuttle blocking the sun's light.

ISS shadow tracking across the orbiter

The image has been postprocessed in RadCAD with the scale on the left representing the nodal heat flux, the view being the shuttle belly. The color scale maximum is 1354 W/m2 which represents full solar heating. As the ISS passes over the shuttle, the resulting shadow or blockage is displayed by the blue color (0 W/m2).

This simulation could have been performed using a raytracer for animated movie rendering but the advantage of RadCAD is that you can obtain a similar result directly applicable for other thermal related computations.

This example of using RadCAD to track IR and solar shadowing has been provided by Igor Carron of the Spacecraft Technology Center at Texas A&M University.

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.
