An ideal strategy of operation can be generated by analyzing the results of the simulation.
The most exact approach to model the entire process is the use of Computational Fluid Dynamics (CFD).
Steady CFD simulations are used to increase the quality of the process model like determining the heat transfer by different operation modes.
The mass per charging is increased by 100 kg at every simulation run.

Abstract.
Numerical simulation on a rough flat plate with a row of 35°round film holes under different roughness heights, Reynolds numbers and blowing ratios is conducted to see how they affect film cooling on a flat plate.
Fluent is a widely used CFD software to handle different kinds of flow and heat transfer problems, and this study is based on the Fluent.
Skewness of the mesh is checked to be found satisfied to the engineering simulation demands. the first depth of the grid must be bigger than roughness parameter ks , so the first depth is 1mm.
After simulation ,results are analyzed in terms of aerodynamics to reveal the effect of the roughness height, mainstream Reynolds number and blow ratio on the film cooling.

FEM for magnetic fields, CFD for fluid flows, are not
or only to a limited extent permissible.
That's why the characteristic maps for the relationship between flow rate or flow force,stroke and pressure difference are sufficiently determinable by a series of CFD simulations.Table 1 summarises the chosen implementation of the identified noise factors for the directional control valve under consideration.
Since the spool position matches for both simulation and measurements, the difference in the resulting flow/signal characteristic curve probably arises from simplifications made within the CFD models, e.g. neglected wall-roughness for the cast iron housing.

Timely detecting the buried pipeline leaks and accurately determining the leak and the law of heat and mass transfer processes in multiphase leak has an important significance on numerical simulation analysis.
In this paper, theoretical knowledge of heat transfer, computational fluid dynamics, fluid mechanics , etc. was used to select the appropriate method for calculating the numerical simulation of multiphase flow for buried pipelines for oil-water-gas in the low temperature multiphase flow ( volume ratio 10:1:89 ) leakage process by using computer simulation, to analyze the impact of high viscosity and low viscosity properties on the physical properties of the oil phase of the multi-phase leakage process and to simulate the process of the leak by the use of CFD software.
Numerical simulation of the regional dimensions is 20m × 10m.
Multiphase flow leakage process conditions of high viscosity of the oil phase viscosity resulted that the oil phase can not be gathered in the top of the water phase in a short time, and hindered the trend of crude oil leaking to the surface. 2) Buoyancy produced by density difference can be overcame in a short time in the process of multiphase flow leakage of high viscosity of the oil phase, so that the oil phase gathered at the bottom of the mouth, resulting that the leakage of crude oil penetration area above the buried pipeline was water phase, which was different from the low viscosity conditions multiphase flow leakage during penetration of oil spill area. 3) The impact of oil viscosity conditions on heat and mass transfer processes can’t be ignored when numerical simulation of the leakage of multiphase flow of buried pipelines in cold regions was conducted.
