Hello, I am wondering whether an Archimedes screw generator would work in a pulsating environment. What I mean by this is does the screw require constant flow in order to generate electrcity? Or could I put such a screw in a pressure driven yet zero-head environment(similar to blood flow)? Also, what is the equation for the amount of power such a screw would generate in relation to it's size, surface area, inclination, pressure and speed of the fluid passing through it? Thank You.
