Study of temperature equalization in a ventilated room with air supplied through an oscillator

The transient effects that develop when supplying intake air to a ventilated space through a fluidic oscillator were numerically studied. The results of parametric two-dimensional URANS simulations in the Reynolds number range of (5.3–53)·10 3 showed that with an increase in the supply flow rate, the frequency of self-oscillations of the supply jet increases linearly, while the Strouhal number varies slightly: from 3.3·10 −3 to 5.4·10 −3 . The use of an oscillator intensifies air mixing significantly compared to the basic case with a stationary air supply through a slot, which provides almost uniform temperature distribution in the room during cooling.
