New Type

In order to enhance the efficiency of the Savonius rotor, this paper designs a new type of Savonius rotor with a rectifier. By using Computational Fluid Dynamics software to simulate and optimize the various parameters which affect the efficiency of the rotor. The sliding mesh method is applied here. The Cp-λ curves of wind turbine with different structural parameters are obtained after numerical simulation of flow field. On this basis, this paper gets the optimal structural parameters. And the results indicated that this new type of Savonius rotor has great improvement of efficiency compared with the traditional Savonius-type rotor.

The unique atrium space design brings different visual perception to people, and rational atrium structure has a good influence on natural lighting and energy consumption. The lighting atrium has been widely used in public buildings. This paper aims to optimize the atrium design of public buildings. Some factors such as atrium aspect ratio, light transmission coefficient of the glass and atrium shape etc, were probed in through numerical simulation, which analyzes lighting influence of various lighting atrium forms. On this basis, this paper draws some conclusions, such as daylight factor of atrium space distribution characteristics and its relevance of atrium space geometry, proposes some optimization strategies of architectural lighting atrium, try to provide some guidance in the atrium application of public buildings.

Clamp Force

The quality of the green and the shaping efficiency are affected by the mold structure during the course of powder injection molding (PIM). Based on the numerical simulation, the mathematic model for the optimal design of the gating and runner system in PIM mould is constructed. The method is testified by the Moldflow software and the experiment. From the result, it is suggested that the clamp force and the shape cycle are clearly decreased, the green is densified and the samples’ density error of the green is decreased after the optimal design of the mold structure. Furthermore, the number of trial mold is reduced and the shape efficiency is improved.
