10. Conversion of kinetic energy of air flow created by a fan into useful work.
Tests of interaction between work items with a pilot plant with a stream of air from the fan took place in August - September 2010.
The purpose of the tests:
Working platform installation WHD-2 was set at a distance of 1.75 m, 5.35 m and 8 m from the fan in front of the outlet fan.
The length of the crank during the aerodynamic testing Lcr = 185 mm. and the amplitude of the reciprocating movement of the working elements of the "A" in accordance with the formula (7).
Work items are in the form of plates of rectangular shape with the following parameters:
- Width b = 410 mm.
Area of work items during the aerodynamic testing in accordance with the formula (11)
The area of contact with the air flow (cross-sectional area that interacts with the air flow, defined by (limited) the reciprocating movement of the working elements perpendicular to the flow of Fig. 6) fluctuations in the work items in accordance with formula (12)
Sc = 0.525 sq.m.
Power flow of air created by a fan at a distance «L» the fan defined in paragraph 6.3, meaning that the calculated power is conditional, acting only on the first working element installation. The kinetic energy of the flow of air from the fan, acting on the second and subsequent work items that are reduced in accordance with the schedule shown in Fig. 18.
