Abstract: A hydrofoil blade for use in a paper making machine wherein a plurality of variously angulated surfaces is provided for producing turbulence having controllable scale and intensity while independently controlling the rate of dewatering.
Abstract: A hydrofoil blade and support for use in a paper making machine, and a method using a hydrofoil blade for dewatering and forming a paper web on a paper machine forming medium wherein a single phase fluid is formed in a gap between the hydrofoil blade and forming medium, and the gap is extended a sufficient distance in the machine direction to prevent expansion and corresponding cavitation of the single phase fluid in the gap.
