Title of the articleExperimental study of the device with the impeller for stabilization of the ventilation air flow
Abstract.An experimental study of a new design model of the device with the impeller, which is intended to stabilize the ventilation air flow, is done. The main elements of the device are: impeller, perceiving the impact of air flow, connected to segment valve, which regulates device resistance and an elastic member that restricts the angle of rotation of the impeller with valve. On the stand measured the pressure loss in a model of the device at certain air speeds in the channel and angles ? of rotation of the impeller with a segment valve. Rotational moments from the air flow effect on the impeller, are measured. Results are presented as the dependence of the pressure loss factor of coefficient ? of the device and the steering angle and ratio k, which characterizes the rotational moments. The results are shown as the formulas and graphs. Relative error is within 9 %. The obtained data can be used for designing and calculating geometrically similar devices. Stabilization of ventilation air consumption, for example, in natural exhaust ventilation systems reduces significantly the cost of heat energy to heat of an excessive amount of air, that provides expediency of investments in such devices.
Keywords.experimental study, air flow, the device for stabilization, impeller, pressure loss.
