Progress in numerical simulation of tropical cyclones is carefully reviewed. Modern, three-dimensional models succeed in simulating observed features such as the eye and spiral rain bands and in predicting storm motion over time intervals of three days. Current capabilities to predict and modify hurricanes and tropical cyclones are fully examined.

Abstract. The steering principle of tropical cyclone motion has been applied to tropical cyclone forecasting and research for nearly 100 years. Two fundamental questions remain unanswered. One is why the steering flow plays a dominant role in tropical cyclone motion, and the other is when tropi-cal cyclone motion deviates considerably from the ...

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …

The medium used in the cyclone filter during operation is water containing solid particles, which contains two types of solid particles. As shown in Fig. 2 (a) and (c), one type is the spherical particle with a diameter of 2 mm and a sphericity of 1. The other type is the flat particle, with an equivalent diameter equal to that of the spherical particle.

Cyclone separator is a type of sedimentation technique that works on the principle of centrifugal force rather than gravitational force. Thus, based on the fluid velocity, a cyclone enables the separation of all the particles or only the coarse particles can be removed, leaving behind the particles which are then carried away by the fluid.

Operating Principle. In a cyclone separator, the incoming air stream, containing particulates, is injected at a high velocity into the cyclone's cylindrical section which initiates a rapidly spinning vortex. Due to the cylindrical and conical structure, larger and heavier particles gain higher inertia than the air.

Principle of Cyclone Separator: In the cyclone separator, the centrifugal force is used to separate solids from the fluids (liquid or gas/air). The separation depends on the particle size as well as on the density of the particles. Hence depending on the fluid velocity, the cyclone separator can be used to separate all types of particles.
