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.

Advanced Pipes in FloCAD
Thursday November 14, 9-10am MT (8-9am PT, 11am-noon ET)
This webinar introduces advanced features for FloCAD pipes in addition to working with complex geometry. Complex geometry includes interior fins and surfaces for heat transfer, flow around enclosed objects, annular flow, concentric pipes, and more. FK Locators and TEEs as modeling objects will also be introduced.
Custom Heat Transfer and Pressure Drops
Tuesday November 19, 2-3pm MT (1-2pm PT, 4-5pm ET)
Do you know what the default assumptions are in FloCAD, and whether or not they apply in your situation? Do you know how far you can go past that starting point? The answer: pretty far. There are numerous mechanisms in FloCAD for adjusting factors, scaling uncertainties, and applying different or supplemental correlations. This webinar summarizes the options available to you to customize your flow models to make sure that they apply to each new situation you encounter.
Heat Exchangers: Detailed and System-level
Thursday November 21, 2-3pm MT (1-2pm PT, 4-5pm ET)
This is two webinars in one. The first explains the use and assumptions behind the FloCAD HX system-level modeling object. The second webinar describes detailed-level modeling of complex heat exchanger passages, including application of Compact Heat Exchanger (CHX) methods.
Starting in 2020, we will begin offering Introduction to Thermal Desktop and Introduction to RadCAD as either in-person training or online training, alternating between online and in-person every three months. The training uses lectures and demonstrations to introduce you to basic Thermal Desktop and RadCAD usage. Hands-on tutorials provide practice building models and interpreting results (tutorials are completed by students outside of the online class time).
 
The next training class will be an online format in January 2020:
  • Introduction to Thermal Desktop (and SINDA) - A three-part series on January 14, 16, and 21 from 9am to 12pm, Mountain time
  • Introduction to RadCAD - January 23 from 9am to 12pm, Mountain time
For up-to-date schedules, fees, and policies, visit our Product Training page. To register for the class above, complete our registration form and select "Online" for the Training Format.
 
If you are interested in product training for your company based on your schedule, please contact us to obtain a quote for training between 8-12 attendees. We can come to your facility or the lectures can be presented online. Descriptions of the available classes can be found in our course catalog.
