Generate a computer code to simulate the following solidification situation during a casting process:

The material is a well-known polymer known as PEEK (polyetheretherketone).  The properties of this material are as follows:

K= 0.251 W/mK,      ρ = 1262 kg/m3   Cps = Cpl =1339 J/kgK

                Ts      =3300C =    603K, Tl =3450C  =618 K

                hs = CpsTs =807,417 J/kg, hl Cpl Tl  = 827,502 J/kg

Assume that Tinitial = 650 K everywhere (the pouring temperature) and that at time = 0 the wall temperatures on walls AB, BC, AD, and DC are set to Twall = 290 K (the mold temperature).  Study this solidification problem numerically, and hand in the following:

  • A copy of your source code
  • Plots of Tcenter versus time and Tp versus time
  • The total solidification time and final point of solidification within the product.
  • Contour plots of solidus and liquidus interfaces for a selected time.
  • A plot showing the temporal progression of solidus interface fronts during the casting process.

Run your code several times with a deceasing mesh cell size.  For each of these mesh cell sizes, report on the following:

  • The total solidification time and final point of solidification within the product.

From this mesh size sensitivity analysis suggest an optimal mesh size to address this type of problem.
