Abstract

The contribution describes an approach that can be used during evaluation of a view factor between complex emitter and planar absorber surfaces. Rather than sophisticated mathematical attitude, practical way is offered. The source surface is divided into smaller parts with same surface normal and using some minor assumptions, summary view factor is calculated. The contribution is aimed on an error that can be caused considering these assumptions and further on, on a case study (evaluation of a view factor between ceramic plaques source surface and a photometric sensor), real differences are shown.
