Nanosize Particle

Nanosize particle flow is significantly affected by inter-particle force. Due to the inter-particle force, the most significant characteristic of nanosize particle flow may become the formation of agglomerates or clusters which considerably affects the flow patterns. The formation of agglomerates or clusters results in a reduction in the number and an increase in the size of particles, both of which directly affect the frequency of inter-particle collisions and, in turn, the particle phase properties such as viscosity and pressure, as well as gas/particle drag force in gas/particle flow systems. In this present work, we focus our attention on the verification of nanosize particle flow behavior due to the formation of agglomerates or clusters under different fluctuation of flow and inelasticity of particle collision. By extending the application of the cohesive model using kinetic theory to nanosize particle flow system, we performed the homogeneous simple shear flow analysis using various fluctuation energy and restitution coefficient. The predicted flow properties, such as particle diameter growth, agreed well with the expected trends.

A “two-fluid” model has been applied to predict turbulent dilute gas-particle flow through a Venturi tube. Bulk motion of particles is considered as a secondary fluid flow which exchanges mass and momentum with the primary conveying air stream. Closure of the time-averaged equations is achieved by modelling turbulent second-order correlations with an extended mixing-length theory. Proposed closure model is found to aptly simulate the dependency of the static pressure drop on the particle size, flow rate and the loading ratio.

The particle system has unique advantages on the stimulation of the natural phenomena of rain, snow, flowing water and dust, physical phenomena and space warp. The paper discussed using the event-driven particle flow system to stimulate the fountain on the stimulation of fountain on particle system, in which there are disadvantages of by using the non-event-driven particle flow system and lacking of the effects of external factors such as resistance, gravity and the speed of wind. The event-driven particle flow system is made up of a series of events. Every particle flow emitted the particles that will experienced a series of events. In every event we can use operator to the effect of all the changes in particles. Among the tests in the events, the events are connected together. So we can stimulate the water jetting, falling, spray, ripple and the effect of disappear with the wind of the fountain. All these can prove that the event-driven particle system is necessary in producing the realistic scene.
