Multiphase flow has been extensively involved in the fields of industrial and technology, such as energy, environment protecting, petroleum and chemical engineering, cryogenics and refrigerating, aerospace and so on. The research about swirling gas-solid multiphase flow is an important branch of multiphase flow. It is widely applied in technology field, such as the burner and aerodynamics characteristic of boiler in modern power plant, the gas-solid cyclone of the Circular Fluidizing Bed (CFB), the swirling...
