  • Title: Prediction of facial cooling while walking in cold wind.
    Author: Tikuisis P, Ducharme MB, Brajkovic D.
    Journal: Comput Biol Med; 2007 Sep; 37(9):1225-31. PubMed ID: 17188259.
    Abstract:
    A dynamic model of cheek cooling has been modified to account for increased skin blood circulation of individuals walking in cold wind. This was achieved by modelling the cold-induced vasodilation response to cold as a varying blood perfusion term, which provided a source of convective heat to the skin tissues of the model. Physiologically-valid blood perfusion was fitted to replicate the cheek skin temperature responses of 12 individuals experimentally exposed to air temperatures from -10 to 10 degrees C at wind speeds from 2 to 8 ms(-1). Resultant cheek skin temperatures met goodness-of-fit criteria and implications on wind chill predictions are discussed.
