Abstract

An alternative model to determine the wind influence from themographic inspections is addressed in this paper. A wind velocity dependent temperature reduction factor is developed and applied in order to estimate the target temperature in the absence of wind. The model makes use of only two unknown coefficients, which are identified for each case. Tests were conducted in laboratory using an aclimatiezed chamber developed to simulate actual conditions, as well in the field. The results of application were also compared to those obtained from other researchers, showing very good agreement.
