Optimal design of the cooling plunger cavity
- 106 Downloads
An axisymmetric system of mould, glass piece, plunger and plunger cavity is considered. The state problem is given as a stationary head conduction process. The system includes the glass piece representing the heat source and is cooled inside the plunger cavity by flowing water and outside by the environment of the mould. The design variable is taken to be the shape of the inner surface of the plunger cavity.
The cost functional is the second power of the norm in the weighted space L r 2 of difference of trace of temperature from given constant, which is evaluated on the outward boundary of the plunger.
Existence and uniqueness of the state problem solution and existence of a solution of the optimization problem are proved.
