A Multiscale Approach to Simulate Vacuum Drying of a Packed Bed of Spray-Frozen Particles

Lorenzo Stratta¹, Roberto Pisano¹, Merve Betul Adali¹, Gianluca Boccardo¹, Antonello Barresi¹, Agnese Marcato¹, Raffaele Tuccinardi¹
¹Politecnico di Torino, Torino, Italy

Preservation of biopharmaceuticals by spray freeze-drying is of great interest as it involves gentle drying and can be easily integrated with continuous manufacturing strategies. The drying of packed beds have been extensively studied experimentally, but a detailed mathematical model of ... En savoir plus

High Fidelity TEA Theory Altered Compressible Navier-Stokes CFD Using COMSOL Equation-Based Modeling

James D Freels¹, A. J. Baker²
¹University of Tennessee, Knoxville, MABE Department, Adjunct Faculty
²University of Tennessee, Knoxville, MABE Department, Professor Emeritus

It is common knowledge to readers of these COMSOL conference proceedings that COMSOL (as well as other established CFD codes) produces unstable numerical solutions of the Navier-Stokes equations without "consistent stabilization" and/or "inconsistent stabilization" (or similar ... En savoir plus

Analysis and Comparison of Modeling Approaches for Heat Pipes

L. Fromme¹, N. Peick¹, L. M. Sommer¹
