Teaching Materials (1-6 of 6)

  1. Crystal-free Zone in a Glass-Ceramic Dish

    28 May 2019 | | Contributor(s):: Adam Powell

    Estimate the thickness of the crystal-free surface layer in a glass-ceramic dish by relating a heat equation solution to the T-T-T diagram.

  2. Freezing by Radiation and Convection

    16 May 2019 | | Contributor(s):: Adam Powell

    Use radiation and a heat transfer coefficient to estimate the initial rate of solidification of the solid shell at the top of a casting while the temperature in the shell can be considered uniform, then set up the equation for mixed conduction/convection-radiation limited cooling.

  3. Heat Conduction and Diffusion in Alloy Casting

    16 May 2019 | | Contributor(s):: Adam Powell

    Derive temperature and liquid concentration profiles during die casting of a roughly plate-shaped alloy part.

  4. Radiative Cooling of an Aluminum Cube

    09 Apr 2019 | | Contributor(s):: Adam Powell

    Show that radiative cooling of an aluminum cube is Newtonian (uniform temperature), and calculate time required to cool through a certain temperature range by radiation alone.

  5. A Heat Transfer Calculation

    20 Mar 2019 | | Contributor(s):: Adam Powell

    Outline the steps required to calculate the temperature at the interface between a stationary solid and a fluid flowing past it.

  6. Argon Quenching of Ni-based Alloy Cylindrical Bars

    20 Mar 2019 | | Contributor(s):: Matthew John M. Krane

    Calculate radiation viewfactors and power transferred between various parts of an zirconia physical vapor deposition chamber.
