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
  • ….
