WebJan 3, 2000 · It is shown theoretically and computationally that there is a critical pre-swirl ratio, β p, crit, for which the frictional moment on the rotating discs is zero, and there is an optimal pre-swirl ratio, β p, opt, where the average Nusselt number is a minimum. WebAt present, the ventilator does not need an external high-pressure gas source because the internal turbine is used as the gas driving source. It is widely used in places where there is little or no high-pressure gas source in the field and small and medium-sized hospitals without central gas supply.
