A study has been carried out for the purpose of clarifying spray performances of highly concentrated coal-water mixtures (CWM) and obtaining a guide for the design of practical twin-fluid atomizers. Disintegration mechanisms and spray characteristics were investigated on the simple twin-fluid atomization of CWM, and compared with those of single-phase liquids. Furthermore, these disintegration model. In the disintegration of a CWM jet by high-speed air, atomization phenomena are similar to those of low-viscosity liquids. Spray is generated basically by the tearing-off of irregularly shaped small drops from the jet surface and by the splitting-up of the unstably fluctuating jet into spherical drops. With the increase of air velocity, Sauter's mean diameter of spray decreases steeply, but its manner depends on the disintegration mechanism.
