This study proposes a novel and systematic approach for PP analysis that integrates mathematical and numerical techniques to determine the unknown outlet state of a target stream based on the known states and a predefined PP temperature difference that constrains the streams. The methodology employs polynomial functions of temperature-specific enthalpy relationships, transformed into dimensionless enthalpy-based expressions, enabling an iterative process to precisely identify the minimum temperature difference between streams. Verification against existing analytical and numerical methods demonstrates the superior accuracy and computational efficiency of the proposed approach. A comprehensive parametric study further reveals the impact of mass fraction, working pressure, polynomial degree, and numerical tolerance on PP characteristics.

In this study, a CFD-integrated drying model was developed to investigate drying uniformity for multiple samples under various conditions. This includes investigating whether a meshed inlet can enhance airflow distribution, thereby improving both drying uniformity and drying rates. Moreover, the study examined the uniformity of air velocity, moisture content, and sample temperature for different sample arrangements and positions within the drying chamber. Results indicated that higher air velocities significantly enhance moisture removal and temperature uniformity among samples, while sample placement notably affects drying rates. Moreover, the inclusion of meshed inlet can reduce the low energy spots within the drying chamber for optimizing the drying efficiency of the system. However, higher uniformities in air velocity and sample temperature, and moisture content were achieved from the non-perforated air inlet.
