PEN simulations

MUPUS Team Meeting, October 2013, Graz


Comsol model
COMSOL Model

  • FEM

  • 2D-axial symmetric  cylindrical shaped geometry

  • Finite dimensions

  • Cooling curve not included







Summary
Summary

  • Better values for PVC, in general to high for Rohacell

  • Upper sensors higher deviation from the measurement values (to high in case all sensors are heated, to low if only a few sensors are heated)

  • Values and shape of curve depend on the ambient temperature and emissivity of the upper part


To do list
“To do list”

  • Checking the values for the thermal properties of the single sensors

  • Checking thermal properties of the tube

  • ….
