Study the Distance and Flow Direction Effect on Air Control between Two Air Curtains

Two air jet curtains can enhance the ability of tunnel air control, but the interactional influence between two jet bring side-effect at the same time, this side effect changes with jet flow, space size, which may harm the ability of tunnel air control in disadvantage situation. This article use FDS to simulate flow pattern of two air jet in different situation, get stability condition and air control ability in different jet situation which can provide guidance for air jet, air control engineering.
