Abstract

Liquid-crystal thermography based on wide-band liquid crystals, a colour-video system and a new vacuum bonded composite laminate is used to provide full-field, highly accurate wall-temperature measurements. In a prototype experiment natural convection heat transfer at an inclined flat plate in the presence of longitudinal vortices is investigated. The local distribution of heat-transfer coefficients is compared with the results of a numerical analysis.
