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...
In the process of air blower design, splitter blades could be adopted in the middle of rotator to improve the air blower performance. In order to understand the flow pattern in the high-pressure centrifugal blower of 9–26 type with splitter blade thoroughly, the three dimensional air flows in the air blower is numerically simulated and analyzed with computational fluid dynamics. Standard k-ε turbulence...
This paper details an innovative design for a wave energy harvester that converts the heaving motion of waves into electrical power. The conceptual design utilizes a unique bi-directional turbine system that develops a torque in a given direction, independent of whether the fluid is moving upward or downward. The result is power production both as the buoy is heaved upward by a wave as well as while...
There is a new way, using FLUENT--a computational fluid dynamics software, to analyze the inside flow field of hydraulic retarder instead of using one-dimension flow theory. In the simulation process, the inside flow field is assumed whole fluid-filled. And the moving areas use sliding mesh model while the turbulence model chooses standard two equations model. Finally, there are analysis of the pressure,...
The numerical solution of flow field in hydrodynamic coupling is calculated with three-dimensional flow numerical simulation method of computational fluid dynamics (CFD) and the typical flow field is analyzed. Based on the 3-D flow numerical solution, the original characteristic of hydrodynamic coupling is predicted. The result indicates that the prediction accuracy of characteristics which is based...
