Abstract—Heating and cooling process for three dimensional pouch are presented and analyzed in this work. Profiles of transient temperature and the form of Lowest Heating Zone (LHZ) and Lowest Cooling Zone (LCZ) are also analyzed and studied. The process of heating and cooling are simulated for 3200 s and 1000 s respectively. Computational Fluid Dynamics software package PHOENICS was used in this study. Saturated steam at 121oC is used for the heating process and water at 25oC, for the cooling process. The governing equations (Navier Stocks equations) for continuity, energy, and momentum in three directions are solved numerically using a Finite Volume Method (FVM). Viscosity and density of liquid model are assumed temperature dependent. At the end of heating, the LHZ is settled around 30% of pouch’s height from its bottom, while in the process of cooling, the LCZ is gradually transferred towards the wide end of pouch at around 70% of pouch’s height from its bottom.
