Problems: Unsteady state heat conduction (Chapter 5; Datta, 2002 )

Calculation tools:

  1. Applet for transient heat conduction in semi-infinite solid. (convection BC)
  2. Applet for transient heat conduction in a plate (symmetrical convection BC; first order; same solution as in Heisler; good approx. for Fo >0. 2)
  3. Applet for transient heat conduction in a plate (symmetrical convection BC; higher order solution for smaller Fo-numbers)
  4. Spreadsheet for reading of Heislergraphs with convection BC:
    1. Heisler B1 (Plate) (Datta, 2002, page 327)
    2. Heisler B2 (Cylinder) (Datta, 2002, page 328)
    3. Heisler B3 (Sphere)  (Datta, 2002, page 329)

Animation of the first order approximation of the transient plate (prescribed wall temperature and half the thickness; check the Fo -number  ) (version embedded in webpage but not all browsers work correctly)
