  8. Review of Heat Transfer Caroline Schauer Department of Materials Engineering Drexel University © Caroline Schauer 2007

  9. Steady State Heat Transfer Fourier law • Plane: • Cylinder: • Sphere: © Caroline Schauer 2007

  10. Non-Steady State Heat Transfer Fourier law Few analytical solutions. Numerical solutions via finite elements are easily obtained for complex geometries © Caroline Schauer 2007

  11. Non-Steady State Heat Transfer Plate: Assuming highly effective removal Of heat from the surface © Caroline Schauer 2007

  12. Non-Steady State Heat Transfer © Caroline Schauer 2007

  13. Convection Heat removal from surface due to moving fluid © Caroline Schauer 2007

  14. Convection limited cooling of an infinite plate Tw=temp of cooling medium Convection limited Conduction limited © Caroline Schauer 2007

  15. Convectionhow to determine h? To compute the convection coefficient evaluate properties at average temperature © Caroline Schauer 2007

  16. Thermal diffusivity of polymers is LOW © Caroline Schauer 2007

  17. Semicrystalline Amorphous Thermal conductivity © Caroline Schauer 2007

  18. Recall that conductivity -> steady state diffusivity -> transient Note the dip in diffusivity Around melting point © Caroline Schauer 2007

  19. Specific Heat © Caroline Schauer 2007

  20. Specific Heat – Effect of fillers (glass fibers here) © Caroline Schauer 2007
