On the Flow near the Leading and Trailing Edge of Cascades

Abstract

This original papers are consist of three short paragraphs. In the first paragraph, according to the assumption by F. Weinig, a method for calculating the pressure distribution around the leading edge of cascades is developed, and the forms of leading edge are discussed by some numerical examples. In the second, the additional losses and the deviation of outlet flow angle owing to the blade thickness at the trailing edge are researched experimentally, and in the last paragraph, an example of strict solution for β₂-t/L curve in cascades (β₂ : direction of outlet flow, t/L : pitchchord ratio), which is composed of some specially formed blade section, is derived theoretically.
