In this paper,CFD was applied to analyze the Impacts of screw speed on all-metal screw pump.
1 The Establishment of All-metal Single Screw Pump's FEM
1.1 Creating Geometric Model
The model number GLB160-10 screw pump was taken for example in this paper.
But the well daily oil production is changing, now the screw speed is choosing according to two method as follows, one is IPR curve, the other one is regular annular measurement or the pressure signal measurement of the well bottom which can measure the liquid level accurately[6,7]. 3 The Result of Simulation under Different Screw Speed Contour graphs of pressure differential between every stage is shown in Fig.4.

Optimal simulation for large dynamic systems
Robert E.
When a model is selected for simulation, it is tempted to believe that the higher the model order, the more accurate the simulation result.
This myth has driven the efforts to use computation-intensive tools, such as computational fluid dynamics (CFD) and finite element analysis (FEA), in system modeling, which usually generate simulation models of tens of thousands or even millions of order.
Therefore, both the dimension and the realization of the simulation model can influence the performance of a computational simulation.
A fixed point digital simulation problem is considered.

A step
further would be to use Computational Fluid Dynamics (CFD) to simulate the compression but this
would need to be an iterative process because the CFD, in itself, requires the assumption of a rheology
model and the input of parameters.
Transient Behaviour Computational Fluid Dynamics (CFD) has been extensively used to predict die filling (see eg. [2]).
Kumar et al [25] and Koke and Modigell [9] however, find shear thickening 'iso-structural' flow behaviour and the latter authors argue that this finding is of high importance for simulation of the industrial process.

The tide simulation for the Sunda Strait is depicted in Figure 1.
Simulation Tidal current speed at Sunda Strait Currently, the high potentioal to develope is Vertical Axis Marine Current Turbine (VAMCT).
Future work could include developing a 3D Discrete Vortex Method solver, modeling airfoils using different curve methods like splines or Bezier curves, defining a boundary for airfoil coordinates optimization, using CFD as a solver to determine the power coefficient of a new wind turbine, and conducting experimental research on the ideal Savonius airfoil, among other things [8].
