Ventilation of enclosures by induced convection of air in turbulent flow regimes
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.
