title = "Calculation methods for the ventilation with solar chimneys: Comparison of analytical models, simulations and measurements",
abstract = "The use of solar chimneys for natural ventilation could contribute to a reduction of the energy consumption of buildings. For the design process of solar chimneys, it is necessary to be able to predict the ventilation effectiveness precisely. In this paper, different analytical equations are compared to results from computational fluid dynamic simulations and experimental measurements. It was found that the investigated analytical methods neglect the occurrence of backflows which leads to an overestimation of the air flow for chimneys with a large depth. For an accurate result, detailed calculations with an adapted discharge coefficient are required to account for this effect.",
