A 3-D numerical heat and mass transfer model for simulating the vibration effects on drying process

摘要

The high-energy costs in the drying process highlight the employment of vibration which is a promising way to intensify this process. This work presents a three-dimensional (3-D) numerical version that exhibits the coupled heat and mass transfer phenomena posed by the external vibrating flow of hot air during the drying process. In order to simulate 3-D vibrating drying, a 3-D unstructured control volume finite element method is developed to analyze the heat and mass transfer during unsaturated porous media drying. Numerical simulation results, which depict the effects of the external vibrating flow which forces the drying process to occur more rapidly and intensively than ever before, are presented and analyzed.
