A Study on the Cross-Flow Turbine in the Pipe Line : Effects of the Effusion Side Casing Form : Series B : Fluid Engineering, Heat Transfer, Combustion, Power, Thermophysical Properties

In recent years the study on a Cross-Flow Turbine has been done by many reseachers. The purpose of this experiment is to recover energy by incorporating this Cross-Flow Turbine into a pipe line (for example, waste water, sewage plant effluent), that is, "reutilization of energy". This turbine has the features that the axes of both entrance and exit pipes and the center of turbine are on the same straight line, and it has considerably simple structure without moving parts. The effusion side casing form is determined by the length of cutwater and the effusion side open angle. Consequently we obtained a maximum efficiency of 78.4%. Improvement is expected by use of the experimental data for the flow condition of a turbine exit.
