Prediction of natural ventilation in buildings with large openings

摘要: Abstract This paper first presents a consistent pressure-based formulation for natural ventilation of single-zone and multi-zone buildings with multiple openings. Pressure-based is made easier to implement by introducing an auxiliary concept external pressure, which allows all the formulas be presented in integrated form. Multi-zone situations considered include vertically interconnected zones, horizontally zones same heights different heights. The includes combined effect wind, thermal buoyancy mechanical ventilation, it can used both internal large A simple easy implementation method was then presented. Single-zone analytical solutions are revisited or developed formulations validation method. CFD also cross-check building very reasonable agreement has been found between results predicted those methods.
