Abstract

This paper describes the relationship between hydraulic losses and secondary flow within sinuous conduits with complicated bends. It has been found that the nature of secondary flow present in the bends is quite sensitive to the geometric configuration of the bend and the actual aspect ratio of the conduit section. Indeed, many different secondary flow patterns have been found to exist as the bend geometry is altered. A wide range of experiments has been conducted for various aspect ratios of a rectangular conduit with different curvatures.

3. Studies of a microcomputer control method for a microhydropower system

Author

Yoshiki Futaki, Tatsuya Sano, Iwane Simaji, Yukimaru Simizu, Sadao Kuzuhara, and Kousaku Morimoto

Subjects
Microcomputer control, Computer science, Mechanical Engineering, Microcomputer, Control engineering, Condensed Matter Physics, Control methods
Abstract

This paper describes a control method for a microhydropower system using a microcomputer. This method is different from that of large-scale hydropower plants. The theory and experimental results of this two year investigation are included in this report.
