University Hospital Crosshouse. The ICU. Airflow patterns revealed.Spread of airborne pathogens.
Conclusions.
CFD – an overview
CFD – enables solutions to be found to complex fluid mechanics problems using numerical methods.
Capable of modelling air flows and their interaction with surfaces.
Capable of modelling the transportation of particles and the effect of heat sources on air flow patterns.

Conclusion CFD model of ICU at University Hospital
Crosshouse.
Visualisation of airflow patterns and spread of respirable pathogens.
Even in this simple study great complexity is revealed.
Use of CFD to complement infection prevention studies.
