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.
Heat Conduction and Diffusion in Alloy Casting
Derive temperature and liquid concentration profiles during die casting of a roughly plate-shaped alloy part.
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.
