Experimental study on the flow field and economic characteristics of parallel push-pull ventilation system

open access: yesEnergy and Built Environment, 2020
Push-pull ventilation systems provide excellent control of contaminants and harmful gases. However, since both a push inlet and a pull outlet are used in the push-pull ventilation system, the flow rate required by the system is large.

Simulation of the Flow Field Characteristics of a Downburst [PDF]

open access: yes, 2007
Wind load on a structure is usually investigated in turbulent boundary layer flow simulated in a boundary layer wind tunnel. However, the strong wind that causes damages on structures is usually transient wind, for instance, downburst wind, whose statistics are different with the general atmospheric boundary layer.
