Numerical Simulation of Flow and Temperature Field in Test Tube of Model Loop Wax Deposition Apparatus;

According to the basic equations of one-dimension gas flow, a hole model for calculation of hole leakage rate in adiabatic process and a pipeline model for calculation of leakage rate in variable process suited to full rupture of pipeline are deducted.

A new fluvial model, including the description and modeling of branching and intercrossing, is put forward.

A new fluvial model characterized with description and simulation functions for branching and crossing streams was presented.

According to the operation characteristics, two models that are the flue model and the heat- transfer model have been developed with an aim of solving the problems involved in the flue structure design and in the temperature curve controlled by computing simulation.

dart inserting,with a presentation of corresponding fabric and dart models, as well as calculation for removing the deformation.

Application of stochastic trajectory model in tail-nozzle SRM flow field numerical simulation;

It is suggested that the part ide- motion- resolution trajectory model is efficient for simulating the dynamic behavior of circulating fluidized beds.

In order to provide analysis results for fault diagnosis in a tailpipe nozzle to make some suggestions,twophase flow field is studied for a tailpipe nozzle by using the trajectory model and finite volume method to obtain the gas temperature and Mach number distributions,and to simulate the collision between the wall and different size particles under different total pressures.
