Abstract

Highlights
•Human thermal boundary layer is found to be penetrable at velocities lower than normally recognized value.
•Reduced challenge of penetration allows for a more effective delivery of fresh air.
•Performance of PV is significantly affected by the flow interactions in the confined space around human body.
•This study implies the interactions should be important considerations for optimal ventilation design.
