Reduced Scale Experimental Study and CFD Analysis on the Resistance Characteristic of Utility Tunnel's Ventilation System. (February 2019) - Li, Shu
Abstract: An experiment model is established with the geometrical scale of 5:1 based on an actual utility tunnel engineering, and the air volume is deduced with Re similarity principle. Besides a corresponding numerical simulation model is set up. Through the comparison of the results of experiment and the numerical simulation, the errors are under the allowed error of engineering. The fitted formula between friction resistance and Re may help in the future design and type selection of utility tunnel's ventilation system.
