  1. CD Injection Molding I: Navier-Stokes

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

    State simplifying assumptions which can be made regarding radial injection molding of liquid polycarbonate polymer into a CD mold, and simplify the cylindrical form of the Navier-Stokes equations accordingly.

  2. CD Injection Molding II: Shear Stress

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

    Solve the cylindrical Navier-Stokes equations simplified in Part I to give the velocity profile in radial injection molding of a CD, and calculate the shear stress based on this velocity profile.

  3. 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.

  4. Bottom Filled Mold

    07 Apr 2019 | | Contributor(s):: Matthew John M. Krane

    Calculation of mold filling times, with and without a constant height of metal in a riser. Problem uses modified Bernoulli equation for the mechanical energy balance and the students are asked to determine which resistances are significant.
