Presentation Transcript

  1. PEN simulations MUPUS Team Meeting, October 2013, Graz

  2. COMSOL Model • FEM • 2D-axial symmetric  cylindrical shaped geometry • Finite dimensions • Cooling curve not included

  3. mupus4.stp

  4. PVC

  5. Thermal conductivity

  6. Rohacell

  7. Thermal conductivity

  8. 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

  9. “To do list” • Checking the values for the thermal properties of the single sensors • Checking thermal properties of the tube • ….
