A novel low-resistance tee of ventilation and air conditioning duct based on energy dissipation control

This study demonstrates that the novel tee constantly maintains the least resistance under different flow ratios (5:1 to 1:3) and aspect ratios (4:1 to 1:4), compared with five other traditional tee types. Moreover, the resistance can be reduced by 42% compared with the traditional tee. The use of the novel tee reduces energy dissipation intensity, and the energy dissipation area is pushed away from the main flow area.
