Experimental verification of induced ventilation Academic Article uri icon


  • The present technical note continues the study of induced air flow inside structures as an effective means for ventilation of enclosed spaces. The air flow is caused by natural convection in a heated duct which absorbs solar irradiation outside the building. Experimental studies have been performed in a real-size mobile home. The experiments included temperature and velocity measurements. Three-dimensional computer simulations have been performed using a standard k-ε turbulence model. The results indicate that effective ventilation by the proposed method can be obtained in a properly designed structure, even at low absorbed heat fluxes. Journal of Environmental Engineering
