Once the exit velocity in the coil tubing is known, the value is used as an inlet velocity boundary condition for the bottomhole and the well annulus for the subsequent CFD analysis.
The bottomhole and the cased annulus flow parameters are solved using the CFD software, FLUENT.
The present approach resulted in approximately an hour per simulation time.
The simulation utilizes the FLUENT Eulerian-granular multiphase module as its basis.
It can be helpful to CT crew in-situ without the need of detail simulation model.

Two-dimensional flow field simulation of two-wing synchronous rotor and four-wing synchronous rotor mixer were studied and the simulation computation of the fluid-structure interaction in a real sense were realized with FEM software.
The FSI in ADINA is the real fluid-solid coupling instead of the pure movable boundary of the ordinary CFD software.
For the simulation process is in the late stage of mixing, it is assumed that the rubber tends to a uniform melt flow, and the force on the rotor will be very small and the waterway structure among the rotor will not affect the overall strength of the rotor.

A numerical simulation has been conducted for concrete pavement on atmospheric thermal environment adjacent to ground under solar radiation.
In this simulation, underlying constant temperature layer was adopted so as to effectively solve the difficulty of specifying the temperature boundary of ground in thermal environment.
CFD software Fluent was used in this numerical simulation.
The interaction between pavement and atmosphere was taken into consideration in this simulation by building up a 3D model including concrete pavement, ambient air and underlying soil.
By comparson of the calculated values with the measured ones, the accuracy of this simulation is proven.

The engineers are most concerned about the optimal design, although the simulation software can reflect the genuine physical properties, but the simulation time is troubling them most.
To solve this problem, simulation optimization emerged algorithm is massively important.
The database stores simulation inputs and outputs, retrieval of existing simulation runs instead of running a brand new simulation when inputs and outputs exist in the database, filtering the experiment data, and comparing stored simulation outputs.
The approach saves the cost of a simulation run when a nearby data point already exists in the database (a simulation run is required if and only if a nearby data point does not exist in the database).
Future work includes applying this approach to high-dimensional design optimization applications using expensive finite-element models and computation fluid dynamics (CFD), and so on.
