Forcing natural ventilation resources in a hybrid ventilated facility at KTH

In this paper a method to solve a design problem of hybrid ventilation system is proposedby building stack pressure around the ventilator using a flat bed, glass-shielded rectangular solarchannel. In support of this idea a CFD (Computational Fluid Dynamics) simulation based ontheoretical calculation is done. Here, natural convection and a k-e two-equation turbulence modelwere used together with the finite volume method. A careful analysis of results was performed in thechannel simulation depending on different boundary conditions and from different channel geometry to find out the best effect. Temperature and velocity distribution was considered in order to have better understanding of the flow pattern changes in the channel. The method was validated against measured data.
