Influences of a square and circular vent on gasoline vapor explosions and its propagation: Comparative experimental study

Case Studies in Thermal Engineering, 2021
Although vents' shapes influence the discharge coefficients, there is a lack of discussions of the vent shapes in vent design guides and explosion-venting investigation. This work carried out detail experiments in a 10 L cuboid vented vessel containing a
