Numerical simulation of ramjet components in isolated mode as well as in completely integrated stage is extremely useful for cost and time-saving when the system is under design and development.
Computational fluid dynamics (CFD) tools are complementary to wind tunnel and propulsion bench tests and these allow one to analyze and optimize more rapidly and at a lower cost.
Different previous researches investigate, both experimentally and by numerical simulation, the vaporizing sprays and the droplet interaction under different operating conditions; see for example references [1-5] In the present study, the efficient mass fraction and the mean diameter of propulsive droplets have been numerically investigated by KIVA-3V code.

The direct numerical simulation (DNS) of Navier-Stokes (N-S) equations seems the most powerful technique to predict the location of transition, for it can simulate the whole transition process.
FLUENT is a general-purpose computational fluid dynamics (CFD) software that ideally suited for incompressible and mildly compressible flows.
Conclusions In this paper, we combined PSE and direct numerical simulation to investigate the evolution of the disturbances and the laminar-turbulent transition in three-dimensional incompressible boundary layer of the infinite flat plate.

With regard to the flow rates of the liquid and air phases, simulation results have shown that these flow rates govern not just the heat transfer and variation of cell distribution, but also the leaching rate regardless of the fraction of CuFeS2 per FeS2 leached (FCP) which is the other variable influencing to the heat accumulation in the heap.
Results and conclusions Following, simulation results with regard to the relation between an intrinsic variable such as the fraction of CuFeS2 per FeS2 leached (FCP) and an operational variable such as the liquid flow (Gl) rate, are shown.

The simulation results show that, this model can well reflect the dynamic and static characteristics of a battery, and the Calman algorithm can keep good accuracy in the estimation process.
Finally, the Matlab simulation results verify the feasibility of this method.
Form the current results of the research, it’s very difficult to describe a battery’ whole performance accurately only using a battery model, so there are various methods to establish the battery model to describe the different types of battery, such as the equivalent circuit model, the electrochemical model, the finite element model, CFD model etc..
Simulation and Verification.
Conclusion From the simulation results we can see, that the EKF algorithm can keep good accuracy in the battery SOC estimation process, have strong corrective action to the initial error of the SOC, and also have certain inhibition effect on the system noise and measurement noise.

Overshoots reproduced by the model simulation output are considered to have the same actual overshoots produced by step response input.
Thus, the simulation models closely follow the actual response of the thruster system.
