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 to the 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 presented 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 the results of infrared imaging in a controlled environment. The wind drift is recorded experimentally and verified using computational fluid dynamics modelling. 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.
