Investigation of a multizone building with HVAC system using a coupled thermal and airflow model [PDF]
E3S Web of Conferences, 2019 In building energy simulations, the air infiltration and interzonal airflow are generally either not considered or calculated oversimplified. However, the effects of air infiltration and building airflow have an impact on the thermal comfort and the ...

Development of a Terminal Control System with Variable Minimum Airflow Rate
Energies, 2012 A constant minimum airflow rate is used in conventional Single Duct Variable Air Volume Terminal Box control sequences. This control sequence can cause occupant discomfort or use excessive energy under partial load conditions. If the minimum airflow rate

Airflow Pattern Similarity Criteria for Ceiling Slot-ventilated Agricultural Enclosures under Isothermal Conditions [PDF]
, 1999 The use of a scaled model can be an effective technique to predict ventilation performance of full-scale prototypes. Many criteria have been proposed to predict the behavior of airflow in a scale model and a prototype.

Supra-orbital whiskers act as wind-sensing antennae in rats.
PLoS Biology, 2023 We know little about mammalian anemotaxis or wind sensing. Recently, however, Hartmann and colleagues showed whisker-based anemotaxis in rats. To investigate how whiskers sense airflow, we first tracked whisker tips in anesthetized rats under low (0.5 m ...
