Fractal Analysis of Raceway Boundary in COREX Melter Gasifier Model

Abstract:

The raceway boundary is coarse and fragmentized, but all of previous studies are based on Euclidean geometry, which regard the dimension of raceway as an integer. In this paper, particle velocity contour has been developed to define the raceway boundary. The fractal method of calculating raceway size, which describe boundary with extremely un-regular or fragment characteristic, is brought forward in physical model. The result shows that the precise raceway boundary can be obtained by particle velocity contour, and the surface area of ellipsoidal raceway based on fractal is larger than that based on Euclidean.
