Cooling design in the forming operation of the television (TV) panel is important because it significantly affects the part quality associated with residual stresses and productivity. A mathematical model and numerical simulation for the cooling process of the panel has been developed. The renormalization group turbulence model is applied for the jet impinging cooling, and a local one-dimensional transient analysis in the thickness direction is adopted for the part, which employs the finite difference method. The experimental verification shows a good agreement with the simulation results.
