Experimental and numerical investigations of Underground Coal Gasification (UCG) using half-teardrop shape cavity
In this work, the process of Underground Coal Gasification (UCG) was studied experimentally and numerically. The typical cavity of UCG was a half-teardrop shape. Thecoal samples were collected from Mae Moh coal mine, Thailand. The coal type is mainly lignite. To generate the gasification...
