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

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.
