Unlike the usual CFD analysis, the movement of this adjusting mechanism is closely related to the pressure field of fluid, so it must be coupled with CFD analysis to get meaningful results.
Coupled Fluid-Structure Interaction Simulation The work process analysis of variable displacement pump incorporates the rigid dynamics of the adjusting mechanism (or stator in vane pump) and the CFD of liquid [4], which are coupled together.
Coupled Simulation and Experiments The procedures of coupled fluid-structure simulation for variable displacement pump are as following: 1.
The valve has partially opened in experiments, which causes higher evaluation of flow in CFD simulations.
Numerical simulation of the variable displacement pump working process is a two-way coupled fluid-structure interaction, which includes structure dynamics and CFD analysis involving time-varying solution domain.

Thus, this paper presents the simulation based on the computational fluid dynamics (CFD) simulation technology of kerosene pool fire scenario of various pool diameters in both stagnant air and cross-wind conditions.
Besides, for the small size pool, the values, respectively obtained with CFD simulation and Thomas Equation, were in good conformance.
While for bigger size pool, the flame height value obtained with CFD simulation was slightly higher than that obtained with the Thomas Equation (e.g. the value obtained with Eq.1 for the 3-meter-diameter kerosene pool was 5.47m, compared with 5.99m obtained with CFD simulation).
Comparatively, in accordance with the fitting Eq.3 of the CFD computation simulation, the calculating result of the flame tilt with a wind speed uw of 3.1m/s is 35.3°.
And the CFD simulated results is slightly lower.

The purpose of this simulation is validate experimental results that show unusual pressure drop behaviour.
Figure 1 – Flow Loop CFD simulation The geometry of the curved 90˚ bend has been modelled according to the dimensions of the elbow section of the flow loop; the dimensions were retrieved through both precise measurements and 3D scan of the section via three-dimensional photography.
Table 1 shows the physical equations used in the simulations.
This behaviour is investigated via CFD to confirm this result.
Conclusion According to the results for the experimental run and CFD simulation: · The CFD results are valid as they show similar pressure drop behaviour · The Experimental results are explainable by the behaviour seen from the CFD results, as it shows the relative static pressure across the pipe wall surface
