STUDY ON MOVING CHARACTERISTIC OF MIXED-SIZED GRANULATED COALASH

Abstract

 Granulated coal ash has been utilized for sludge to the enclosed bay as a beach sand alternate material and the water improvement effect is observed. In order to design the shoal by granulated coal ash, it is necessary to understand the moving characteristic of the granulated coal ash by flow and waves. However, the detailed moving characteristic in the shoal is not clear. So the moving characteristic at the time of installing granulated coal ash in a shoal is clarified by a hydraulic model experiment. Especially, This paper reports the experimental result about moving characteristic of mixed-sized granulated coal ash by the wave.
