CALCULATING RADIATION TEMPERATURE ASYMMETRY BY GRAPHICALLY DETERMINING THE SHAPE FACTOR

Abstract

The specific figure of radiation temperature asymmetry is highly influenced by the shape factor, the used calculation method and the type of the element examined. In addition to the regular calculation methods this paper presents a new drawing method that determines the shape factor based on geometrical surface ratios. This process has been further developed in a way that the used examination plane will always be adequately placed in line with the specific arrangement. To ensure the quick completion of the drawing a programme fitting a mathematical software package has been developed. It is good to use to calculate the values of radiation temperature asymmetry and provide their graphical presentation.
