  1. Radiation in Hall–Héroult Cell Aluminum Smelting

    29 Aug 2019 | | Contributor(s):: Adam Powell

    Estimate heat flux from the graphite anode of a Hall-Heroult cell for smelting aluminum, and discuss uniformity of temperature across the anode.

  2. Heat Transfer, Cost Modeling and Process Selection

    29 Aug 2019 | | Contributor(s):: Adam Powell

    Case study of polymer matrix composite process selection between resin transfer molding and chopped fiber injection molding, including heat conduction to calculate solidification time and technical cost modeling.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.
