Insight HP3

by Asli Gencosmanoglu, Active Space Technologies GmbH

Thermal analysis of Insite HP3The thermal analysis and design of the Heat-Flow and Physical Properties Probe (HP3) Instrument for the landed phase of the mission have been performed by Active Space Technologies GmbH using Thermal Desktop and SINDA/FLUINT. In the scope of the thermal analysis and design activities, the detailed thermal and geometrical models of each subsystem, as well as the integrated models, are created. Being composed of subsystems which are permanently mounted on the lander, deployed on the Mars surface after landing and deployed into the Martian soil, different external thermal environments are defined for each subsystem for the different phases of the mission, including the mars heating environment modeling. The detailed models are integrated on the simplified lander model and the reduced models of the subsystems are also created to be integrated into the detailed lander model.

Below is a highlight of key Thermal Desktop features used:

  • Temperature-dependent properties
  • Anisotropic material properties
  • Wavelength, temperature, and angle-dependent properties
  • CO2 gas conduction
  • Modeling of convective and conductive heat transfer to the atmosphere
  • Integration and merging of models
  • Radiation analysis groups
  • Orbital heating
  • Mars-based planetary heating, vehicle position as a function of time, latitude, longitude, and altitude
  • Mars-based environmental heating, direct and diffuse solar, albedo, diffuse sky IR, and IR planet shine

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
