Abstract

This paper targets the problems of traditional BIM cloud platforms, such as the single functionality, the problematic two-way transfer of lightweight data, and the difficult control of data security. It is based on the BIM collaboration theory, the cloud computing theory as well as the life cycle theory etc., with the requirements for collaborative management in construction projects as its core in order to build BIM cloud platform lead by the owner. This paper puts forward a system design and implementation scheme for private BIM cloud platforms, which realizes the diversification of cloud platform functions, the bidirectional transmission of cloud data and the protection of data privacy. At the same time, this paper designs the application mechanism of cloud platform based on the life cycle theory to meet the use of BIM cloud platform in the whole process from project decision-making stage to operation and maintenance.

Abstract

Effect of film hole diameter to discharge coefficients and film cooling effectiveness of the lamilloy were experimentally investigated at the blowing ratios ranging from 0.6 to 2.5. Generally, the cooling effectiveness on the test surface is increased with the film hole diameters and blowing ratios increasing, and the variation tendency along the streamwise through the centerline of film holes also keeps consistent. In the upstream, all configurations have a relatively lower cooling effectiveness, however, with the flows to the downstream, cooling effectiveness grows gradually, and the peak values of effectiveness appeared periodically, the position matches the film hole positions. Besides, between the film holes, fluctuation exists simultaneously. By comparison, the cooling effectiveness and discharge coefficients are both increased with the blowing ratio with same film hole diameters, Moreover, under the same blowing ratios, the cooling effectiveness and discharge coefficients are getting higher when hole diameters increase.
