CAM

CAM is a one dimensional Conduction Ablation Model which can either be run standalone, or embedded within an AHM simulation. It provides temperature profiles through the material thickness; along with the outgassing and surface recession for heatshields. The architecture of CAM is based on the STABII implicit model. Multiple material layers and backup material can be considered; with the heating and demise of each layer calculated. Both adiabatic and radiative back face conditions are available.

  • Heating models - CAM utilises the AHM module for the effects of radiative cooling and hot wall enthalpy correction during the heating phase; and convective cooling in the post-heating phase of the entry.
  • Demise Models - CAM is supplied with a selection of demise models, including the appropriate phenomenologies for melting and ablating materials.
  • Materials Library - Like AHM, CAM has an extensible material and gas library. The default CAM material model is a superset of that used in AHM, expanding on the former with additional ablative properties.
  • Modular - The architecture of CAM permits the most appropriate components including the material response to be chosen from libraries at execution time.
  • Extensible - Interface definitions are provided for all key components, permitting clients to construct particular heating models optimised for their specific material behaviour, including ablators and meteorites.
  • Configurable - All aspects of CAM can be configured using JavaScript. This enables sequences and complex conditional scenarios to be scripted and evaluated without resorting to changes in the core engineering simulation.
  • Portable - Written in a combination of Java and JavaScript, CAM is fully supported on Windows, Unix / Linux and OS X.
