This article investigates and presents the influences of geometric parameters of a scramjet exerting upon its nozzle performances. These parameters include divergent angles, total lengths, height ratios, cowl lengths, and cowl angles. The flow field within the scramjet nozzle is simulated numerically by using the CFD software--FLUENT in association with coupled implicit solver and an RNG k-ε turbulence model.

Journal of Computer Science & Technology 2000年第6期15卷 572-583页

This paper presents an efficient algorithm that implements one to-many, or multicast, communication in one-port wormhole-routed cube-connected cycles (CCCs) in the absence of hardware multicast support. By exploiting the properties of the switching technology and the use of virtual channels, a minimumtime multicast algorithm is presented for n-dimensional CCCs that use deterministic routing of unicast messages. The algorithm can deliver a multicast message to m - 1 destinations in [log2, m] message-passing steps, while avoiding contention among the constituent unicast messages. Performance results of a simulation study on CCCs with up to 10,240 nodes are also given.

作者： Zhang Bin Chang Hongxing song jianping 2

Case study of 2D/3D association and feature based parametric variational design techniques applied to piping system in AEC industry is made to integrate the P&ID and 3D piping modules. Object classes shared by both modules contain the identical connectivity information for all pipelines, while the geometric information for 2D and 3D cases are stored separately. Some details about the object-oriented techniques to cope with such a situation are explored.
