Abstract
Prediction of raceway shape and size has always been a challenging task. Based on the previous finding that raceway boundary is an iso-stress boundary, its shape and size has been predicted using a continuum approach. A relation has also been developed to get the stress at the raceway boundary at different blast velocity. Predicted raceway boundary is compared with the experimental raceway boundary/shape and size along with the comparison of theoretical and experimental pressure distribution. A reasonable agreement between the theoretical and experimental raceway shape and size is found. Extension of the work in real blast furnace case is also discussed.
