Abstract
A method and apparatus of controlling the flow of a fluid is disclosed which includes a frame having first and second opposite sides, a plurality of flexible hollow tubular shaped elements positioned so as to extend between the first and second sides of the frame, and a mechanism connected to at least the first side of the frame for compressing opposite lateral edges of the first and second sheets of the flexible elements towards and away from one another so as to flex the first and second sheets of each of the flexible elements towards and away from each other and thus adjust fluid flow spacings between neighboring flexible elements. The method of controlling the flow of the gas includes the step of flowing the fluid between neighboring hollow tubular elements and biasing the first and second splines towards one another so as to flex the sheets of the tubular elements away from one another and towards neighboring tubular elements so as to adjust the opening between the neighboring tubular elements.
