Cui Yan

Associate Professor



Academic Areas: Dispersed Multiphase Flow, Computational Fluid Dynamics, Dry Powder Inhaler

Dr.-Ing. Cui was born in November 1985 at Anhui, China. His research activities focus on the particle-laden flow, i.e. modelling the transport, deposition and resuspension of spherical and non-spherical particles, droplets or bubbles by using direct numerical simulation (DNS), experiment and analytical solution within the framework of Euler-Lagrange approach, with applications such as modelling the drug detachment within the dry powder inhaler, regional deposition of drug particles in the respiratory airway, and settling characteristics of sludge flocs in wastewater treatment.
