Abstract

Research work aimed to prove the cooling effectiveness and efficiency of heating numerically. It was carried out by reconstructing the mold to reduce condensation while keeping the production cycle time. The simulation was done using CFD Fluent, Finite Volume Method (FVM) with a solution method of pressure-velocity, SIMPLE coupling, and second-order upwind discretization scheme. The model's boundary condition represents plastic packaging's production process. The simulation was done to optimize performance during production. Reconstruction and simulation were undertaken. The initial investigation was to produce data for cooling time versus the whole production time. The research result indicated that the average cooling time was 3/5 of the total production time. There were 15.5706 of 26.4206 sec and 15.641 of 26.491 sec, respectively. Further investigation was focused on investigating heat absorption and transfer through cells in the matrix. The porous effect showed temperature gradient reduction between cooled and cooler temperatures by simulation in color. The phenomenon predicted that the Ra contributed to the rate of temperature decrease revealed. There is also an apparent increase in temperature interfaces is evidence. The porous media application with The Rayleigh Number ≥ 105 retained the potential cooling effectivity and heating efficiency. By simulation, a series of discussions of the result of research, the potential may apply in the plastic mold to reconstruct the space and its methods using filling-porous. It is relevant because the heating ability in the phase change of fluid that creates particular characteristics has the potential to make effective cooling.
