Professor Woo-Sik Kim's research lab specializes in the mechanics and transport phenomena in biological and soft materials, with a focus on hemodynamics and crystallization processes. The lab investigates macromolecular transport in arterial walls using coupled mechano-hydraulic and fiber matrix models, aiming to understand how hemodynamic forces influence solute distribution and vascular permeability. Additionally, the lab explores the role of Taylor vortex flows in enhancing crystallization efficiency, particularly in controlling nucleation, growth, and particle size distribution in various crystallization processes. These interdisciplinary studies bridge fluid mechanics, biophysics, and materials science to address challenges in cardiovascular health and industrial crystallization.

To determine the macromolecular transport properties of the tunica media of an artery wall deformed inhomogeneously by the transmural pressure, we combine a simple mechano-hydraulic model based on a two parameter strain-dependent permeability function, which was developed by Klanchar and Tarbell (1987), with a fiber matrix theory. The combined theory allows us to calculate the spatial distributions of porosity, solute partition, fiber radius and macromolecular solute concentration in the media a
This study summarizes crystallization technology when using a Taylor vortex flow. A Taylor vortex is created in the gap between two co-axially positioned cylinders based on the rotation of the inner cylinder. Due to its unique periodic flow motion, a Taylor vortex has a significant influence on the processes of nucleation, growth, and agglomeration breakage in various crystallizations, including reaction recrystallization, drowning-out crystallization, and cooling crystallization. In the gas–liq
