Study on the Influence of Window Type on Natural Ventilation Effect Based on CFD Simulation [PDF]

E3S Web of Conferences, 2023
Good natural ventilation is one of the basic conditions for people to be able to work and live indoors. In this paper, wind velocity, wind velocity non-uniformity coefficient and air age are taken as the evaluation indexes of indoor ventilation condition.
