Study of Wind Chill Factor using Infrared Imaging

Abstract


This paper presents a study of wind chill factor using infrared imaging. Wind chill factor is 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 the literature. The wind chill factor is closely associated with the phenomenon of heat transfer. The convective mode of heat transfer is most dominant in the case of wind chill.

The paper presents infrared imaging results in a controlled environment. The wind drift is recorded experimentally and verified using computational fluid dynamics modeling. The results demonstrated that the rate of heat transfer increases under wind drift. This is evident from the temperature of a human subject captured using Infrared imaging.
