Abstract
In the present investigation, we conduct a comprehensive numericalsimulation to explore the complexities of heat and mass transfer phenomena duringthe vacuum drying process. Specifically, our focus is on the critical third phase ofvacuum drying, which incorporates the heating process. To accurately model thesephenomena, we employed a sophisticated three-dimensional heat equation, formu-lated in cylindrical coordinates, that captures the nuanced dynamics of the system.Furthermore, to ensure the reliability and validity of our model, a rigorous stabilityand accuracy analysis was performed on the finite difference equations utilized inthe simulation. The outcomes of this simulation were then meticulously visualized,offering intuitive insights into the heat and mass transfer mechanisms at play duringthe vacuum drying process. This approach not only enhances our understandingof the drying process but also contributes to the refinement of numerical modelingtechniques in the study of vacuum drying systems.
