Study on the Uniform-Flow Manifold

Abstract

From viewpoint of designning manifold system which distributes or concentrates fluid uniformly, practical method of calculations are given. Starting from theoretical model, brief equations for energy loss and pressure distribution as well as a criterion for judging behaviour of pressure distribution curves are introduced, by use of which required total pressure and pressure distribution are easily calculated. As for the coefficients in the equations, experimental researches were made for many types of branching, including ports. These data and methods were utilized for the design of air ducts in Kanmon Vehicular tunnel ventilation system. Some of the measurement data of the tunnel system are referred to.
