摘要：If high-power machines are used and a large number of people are present, a significant amount of heat will be generated, which forms an upward thermal plume. The interaction problem occurs when the cold jet and the thermal plume meet. This article presents the interaction mechanism between a momentum source and a buoyancy source and deduces the interaction parameter β to investigate the effects of parameters such as the power of the source, the air-supply velocity, plume spacing, and nozzle spacing height. Experiments were carried out to investigate the flow field of the air jet affected by the plume and to validate the theoretical work.
