Аннотация

This paper deals with formulation of general relations to be used in an analysis of passive ventilation of open enclosures. Analytical dependencies are introduced for the change of heating levels and/or under proportional scaling of all elements. Various basic cases are analyzed, including constant temperature or heat flux of the heating element, the effect of dominant local hydraulic resistance, and chimney effect. Verification of the dependencies is done by a comparison with numerical calculations performed using a CFD package.
