A CFD-based approach to optimize operating parameters of a flow-through scintillation cell for measurement of 220Rn in indoor environments
TL;DR: In this paper, the performance of a flow-through Lucas scintillation cell (LSC) for long run 220Rn measurements, depends upon the exact distribution pattern of 220 Rn and its decay products in the LSC which can vary with the design of inlet path and flow rates.

Reconstruction of blood flow patterns in a human carotid bifurcation: a combined CFD and MRI study.
TL;DR: It was found that the geometry of the carotid bifurcation was highly complex, involving helical curvature and out‐of‐plane branching, which resulted in patterns of flow and wall shear stress significantly different from those found in simplified planar carotids bIfurcation models.

Influence of indoor air conditions on radon concentration in a detached house.
TL;DR: Air change rate, indoor temperature and moisture had significant effects on indoor radon concentration, and the results from analytical solution, measurements and numerical simulations showed that increasing air change rate reduces radon level.

Simulation of the concentrations and distributions of indoor radon and thoron.
TL;DR: According to the simulation results, in a naturally ventilated room, the activity distribution of 222Rn is homogeneous except for the places near air diffuser (supply and exhaust) locations, and the concentration of 220Rn exponentially decreases with the distance from the source wall which is considered independently.
