In this paper, on the basis of static stress analysis of the Glider wings, we compare different factors influencing the drag force converted by the glider wings and optimize them by comparing the simulation results with the calculation results. The results shows that the horizontal component force is reach maximum value when attack angle reaches 45°. After that the horizontal component force decreases as attack angle increases. The horizontal component force is gradually increased as the flow rate increases under same attack angle.

In this paper, a novel dynamic de-oiling oil-water separator was proposed, and through Computational Fluid Dynamics (CFD) simulation, the effects of the pressure drop ratio on the separation efficiency and the split ratio were analyzed. The results shows that the separation efficiency initially increased and then held steady as the pressure drop ratio increased, while the split ratio exhibited an approximately continuous linear decrease. Moreover, an optimal combination of properties could be obtained when the pressure drop ratio was set at a specific value, wherein both the separation efficiency and the split ratio worked advantageously.

the miner Anti-fire colloid preparation machine was designed referred to the principle of mixer designing in the chemical industry. The computational fluid dynamics (CFD) program FLUENT was used to simulate the inner flow of the colloid preparation machine which was filled with special fly ash slurry by the MRF method. Results of simulation showed the space of double-leaf arrangement had a significant effect on the mixing result for the double leaf blade high and low overlapping arrangement's mixer and processed the optimal space. The affection of baffle width to the mixing effect was also analyzed and acquired some valuable conclusions. The machine was manufactured based the research and the application verified the simulation's significance.
