To probe into the effects of the interaction of fluid mechanics and particle dynamics in the process of flame synthesis, the simulation of titania nanoparticle synthesis in the turbulent diffusion flame was performed by using the commercial CFD-code FLUENT.

Based on particle dynamics, numerical simulations were conducted to study the three-dimensional (3-D) microstructures of the ferro-fluids subjected to rotating magnetic fields.

1d)and its soluble parent, 238U, was used to study the particle dynamics at three stations in the northeastern South China Sea.

The model,based on the kinetic theory of granular flow which recently is widely used to describe particle flow and simulates both gas phase and solid phase by low Reynolds number turbulent model taking into account the turbulent interaction between gas and particles.

The kinetic theory of granular flow was used to predict the particle fluctuating properties and the sub-grid scale model (SGS) for gas turbulent flow.

The gas-phase and granular-phase velocity distribution and pressure loss were obtained through the numerical simulation of the upwards flow characteristics in the vertical pipe by using an Euler-Euler two fluid model of dense gas-solid two phase flow based on the kinetic theory of dense gases and kinetic theory of granular.
