TLDR
The human body is surrounded by an enveiope of upward-moving warm air which forms a natural convection boundary layer which has been used to visualise this airflow and this visualisation has been complemented by measurements of temperature and velocity within the flow and local convective heat transfer rates at the skin surface.Abstract:
The human body is surrounded by an enveiope of upward-moving warm air which forms a natural convection boundary layer. A Schlieren optical system has been used to visualise this airflow and this visualisation has been complemented by measurements of temperature and velocity within the flow and local convective heat transfer rates at the skin surface.read more

Some aspects of the airborne transmission of infection
TL;DR: It is suggested that currently available techniques involving architectural, ventilation and operational aspects of healthcare provision, when properly applied, can markedly improve treatment outcomes that may otherwise be compromised by hospital-acquired infections involving both bacteria and viruses.

Colour-coding schlieren techniques for the optical study of heat and fluid flow☆
TL;DR: The characteristics and advantages of this unique flow visualization tool are discussed in terms of one- and two-dimensional colour-coding, qualitative and quantitative visualisations, and system sensitivity, range and resolution.

Do surgeons and surgical facilities disturb the clean air distribution close to a surgical patient in an orthopedic operating room with laminar airflow
TL;DR: Airflow distribution in proximity to a patient is influenced by both the surgical facility and the presence of medical staff, and the results indicate that the interaction of thermal plumes from a patient and the downward laminar airflow may dominate the operating microenvironment.
Journal ArticleDOI
Schlieren photography—short bibliography and review
TL;DR: A brief description of the principle of Schlieren photography is given in this paper, followed by a review of variations in the technique and a bibliography is presented which includes references to all the important system modifications and spans a wide range of applications.
Journal ArticleDOI
A Comparison between Temperature-Controlled Laminar Airflow Device and a Room Air-Cleaner in Reducing Exposure to Particles While Asleep.
TL;DR: During a periodical duvet lifting mimicking a subject’s movement in bed, the particle concentration was significantly lower with the TLA device compared to the room air cleaner, which provided a barrier which significantly reduced the introduction of airborne particles into the breathing zone.

Aerodynamics of the human microenvironment.
TL;DR: Preliminary experiments reveal that the human microenvironment has a significantly higher content of microorganisms than the ambient air, and this may be one of the missing links in the natural history of airborne infection and a mechanism in hospital sepsis.
