Description
The bench serves to study and try out processes of interaction of low-pressure single- and two-phase flows with aerofoils, grates, and other objects. Low-pressure air is delivered by a controlled-delivery fan into a pipeline connected to the fan by an elastic spacer. The exit of the pipeline is connected to a work chamber mounted on a rail-guided cart.
Capabilities
- Study of the filtration of a two-phase flow;
- Air filter tryout;
- Aerodynamic drag, force, and moment determination;
- Dust fractional composition determination;
- Testing of screw-type cyclone models.
Advantages
- The self-contained compressor permits long-term rests.
- Various systems for process parameter measurement.
Use
The bench is intended to test screw-type cyclone models.
Using the bench, recommendations are worked out on the choice of cyclone models and a two-phase flow cleaning system.
A cyclone for a heat and power plant boiler has been tried out on the bench.
