Abstract [en]

This paper proposes to use free wind to create suction pressure within a ventilation duct without consuming commercial energy. Like an ejector pump it creates suction pressure placed above the ventilation exhaust, which is used to draw exhaust air from the ventilation system. Discussing the possibilities of this suction cylinder concept in ventilation system is the objective of this paper. Here, a mathematical model was deduced for a suction cylinder and through CFD (Computational Fluid Dynamic) technique result was simulated later compared with theoretical model. GAMBIT was used as a preprocessor and for processing FLUENT, a commercial CFD code, was used for the simulation. Preliminary result clearly shows the positive advantages of using a suction cylinder as ventilation equipment.
