RVCR Wind Power Generators (RWPG)

At higher altitudes, wind flows unrestricted in a laminar flow whereas, at near earth surface, wind speed is lower for no-slip condition and disturbances like buildings, trees etc. As the distance from earth surface increases, resistance to air flow decreases and it results in higher wind speeds. The ground creates friction and turbulence which gradually tapers off at greater heights.

Conventional wind turbines are usually located at places; far away from city, where there is enough room to install them and no danger to populace. Preferred locations are sufficiently windy and have largely constant winds like exposed high areas, hills, or small mountains or coastal/Off-shore areas. Main drawback of these conventional wind turbines is the location constraint, as these systems should be installed away from city or areas of electric power demand. The structure of these wind turbines is quite bulky. It is always difficult to transport components (like blades) of these wind turbines to the specified wind sites, special roads has to be constructed. During the operation, turbine should orient itself against the direction of wind flow. Initial cost of these turbines is quite high, consequently increasing the overall cost of the wind energy. Yawing, furling and stalling demands special drives, this results in complicated structure. Wind turbines are not positive displacement machines, so the flow efficiency is lower.

RVCR wind motor utilizes pressure differential phenomenon at different altitudes (Bernoulli’s principle). As the wind blows over the upper region, according to Bernoulli’s principle, pressure is lowered with increased wind speed; hence the air from the lower region, which is comparatively at higher pressure, when provided with suitable flow path flows rapidly towards low-pressure zone in the upper region. This suction force is utilized to generate power by RVCR wind motors. Air flow from lower to upper region is channeled through stacks. So, the more the height of a building, the more will be the pressure differential and consequently, more power will be generated.

RVCR wind motors can be installed in city itself within the building, so unlike conventional wind turbines, the cost of searching of wind sites, transportation of the components to such remote locations can be saved. Compared to bulky structures of wind turbines, RVCR wind motors are quite compact, easy to handle, and manufacturing cost is also lower. This in turn leads to lower initial investment. While in operation, RVCR wind motor is independent of wind flow direction, so the power is continuously generated even if the wind flow direction is changed. Depending upon the wind speed, the angle between vanes can be set so as to get continuous power supply (An advantage of VCR component). It is a positive displacement machine which leads to higher flow efficiencies.
