About the project

Understanding flow dynamics in human airways is crucial for multiple applications - e.g. predicting the effect of air pollution on human health, optimising drug delivery, or choosing the ventilation pattern for better oxygen delivery while not damaging the lung tissue.

Measurement of flow properties in vivo is difficult, therefore modelling tools are routinely used to understand and predict flow distribution. Validation of such studies requires robust experimental data.

Advances in the 3D printing technologies allowed researchers to perform measurements in life-size realistic airway geometries reconstructed from medical scans. However, comprehensive experimental studies are still rare, therefore the reliability and accuracy of results is unknown.

This is a collaborative project between Coventry University's Centre for Fluid and Complex Systems and Imperial College London. Its aim is to develop an improved methodology for experimental studies of human airway flow, with unsteady flow characteristic to human respiration patterns and a range of geometries in order to isolate and understand the airflow mechanisms in different airway sections and provide validation data for modelling studies. The effect of different flow and geometry properties (turbulence, compliant walls, unsteady flow pattern) will be investigated using a range of flow measurement techniques including hot wire anemometry and particle image velocimetry.
