The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.

The state-of-the-art of chemical process and equipment intensificationtechniques is reviewed. A novel concept of compact industrial furnace isproposed, in which tube with static mixer for partly intensification is determined. 2 A virtual engineering scale-up approach is put forward. The key points toimprove the scaling-up efficiency include two tools: one is rapid generationtechniques for computational models in which a re-use library is built, the otheris rapid prototyping manufacturing, employed for rapid generation forexperimental models.3 The tube is the key component for industrial furnace. Material microstructure,high temperature strength, and casting process of the tube with static mixer arediscussed as compared with those of traditional tube. Some special features ofthe static mixer tube are demonstrated.4 An evaluation method of velocity-based disturbance effect of fluid field wasproposed.
