Wind Chill Effect in Cold Climate: Study of Wind Chill Effect Using Infrared Imaging

Abstract

Wind chill factor is explained as the cooling sensation due to the exposure of wind temperature environment. The wind chill factor depends on air temperature, wind velocity and humidity. Wind chill poses serious health risks. Various wind chill index models are given in literature. In order to understand the wind chill effect, it is important to understand the phenomenon of heat transfer. There are three modes of heat transfer namely conduction, convection and radiation. The convective mode of heat transfer is most dominant in the case of wind chill. Preliminary experiments in cold room at The Arctic University of Norway clearly demonstrates higher heat transfer under wind chill conditions.
