Abstract

To investigate the relationship between three-dimensional characteristics of fissure and coke size, an image processing method was developed for 3D medical CT images to extract fissure surface. The three-dimensional volume of coke fissure showed a poor correlation with coke size, while the surface area of fissure showed a good correlation with size of coke that was not subjected to rotational impact. However, the relationship between coke size and fissure surface area under rotational impact is not perfect, and it may be necessary to consider the effects of smaller cracks.
