| 2 | EFFECTIVE DISCHARGE CALCULATION GUIDE显示文摘This paper presents a procedure for calculating the effective discharge for rivers with alluvial channels. An alluvial river adjusts the bankfull shape and dimensions of its channel to the wide range of flows that mobilize the boundary sediments. It has been shown that time-averaged river morphology is adjusted to the flow that, over a prolonged period, transports most sediment. This is termed the effective discharge. The effective discharge mayo be calculated provided that the necessary data are available or can be synthesized. The procedure for effective discharge calculation presented here is designed to have general applicability, have the capability to be applied consistently, and represent the effects of physical processes responsible for determining the channel. dimensions. An example of the calculations necessary and applications of the effective discharge concept are presented. | D. S. BIEDENHARN,C. R. THORNE, P.J.SOAR. ,R.D.HEY, and C. C.

| 3 | EXPERIMENTS ON FLOW AROUND A CYLINDER IN A SCOURED CRANNEL BED显示文摘The flow pattern around a cylinder, installed in a scourd channel bed, was experimentally investigated. Detailed measurements of the instantaneous 3D velocities were performed by using an Acoustic Doppler Velocity Profiler (ADVP), from which the profiles of the time^averaged velocities and turbulence stresses were obtained. It is shown that the influence of thC cylinder and of the scour hole alters the approach flow; this is essentially confined to the viciulty of the cylinder and to the inside of the scour hole. The horseshoe vortex is measured as a flow reversal inside the scour hole, formed by the downward flow along the cylinder face and the reversed flow at the scour bed. | I. ISTIARTO and W.H.

| 4 | AN EXPERIMENTAL STUDY ON BEDMAKING AND CATASTROPHIC PROCESSES IN ISLAND BRAIDED CHANNEL显示文摘In this paper 4 Principles for developing island braided channels are discussed. Based on those principles an island braided bedmaking experiment is designed by a process-response model with 12 steps and the Lower Yangtze River as an example to be taken. The bedmaking experiment takes 10 runs and 180 running hours and channel changes are described. The paper also analyses controlling factors on island braided channel hydraulic geometries. The catastrophic processes experiment takes 3 runs and 72 running hours. and a special complex-response-nested island forming process by suddenly lowering base level from external excitation is reasonably explained. | Desheng JIN, Project (No 49271013) supported by NSFC programm.

| 5 | BED CONDITIONS OF NON-EQUILIBRIUM TRANSPORT OF SUSPENDED SEDIMENT显示文摘The bed conditions for suspended sediment transport under non-equilibrum conditions are discussed herein this paper. Based on some experimental data and numerical results computed from different bed conditions, it is reasoned that the Dirichlet condition is correct for the process of erosion while the Neumann condition holds for deposition. For numerical medeling with complex flow problems a combination of both is suggested and preliminary calculations are given. | ZHOU, Prof Dr. -Ing.

| 6 | RATIONAL BASIS FOR SUSPENDED SEDIMENT MODELING显示文摘This paper presents a rational basis to model the transport of suspended sediment. The looseboundary condition for 3D models and the adjustment coefficients for both the depth-integrated 2D and laterally integrated 1D models are treated comprehensively. A combination of Dirichlet and Neumann conditions is proposed as the loose-boundary condition. The adjustment coefficient for 2D models is obtained on the basis of the proposed boundary condition and analytical solutions developed for some simple cases of non-equilibrium transport of sediment in uniform flows. The adjustment coefficient for 1D models for natural rivers is further obtained from lateral integration. Comparisons with analytical solutions and a considerable amount of laboratory and prototype data show that mathematical models developed along the proposed line of attack would well simulate the transport of suspended sediment in practical problems. | Jianjun ZHOU, Biniiang LIN and Bingnan LIN Prof, Dept. of Hydraulic Eng., Tsinghua University, Beijing 100084, P.R.

| 7 | 甲烷催化燃烧的实验研究显示文摘在含铂的Monolith催化剂上进行了甲烷的催化燃烧反应。实验表明,室温下必须先用氢气来点火,甲烷才能催化燃烧。甲烷催化燃烧的允许工作温度为900~1100℃,过低的温度导至熄火,过高则会使铂催化剂失活。在实验的反应条件下,甲烷进料浓度范围很窄为4%—6%(体积)。 | 王光润 Prof Eigenberger G | 1997 | 化学反应工程与工艺1997,13,1: | 2 |
| 8 | ON THE PHYSICS OF FLOW-DRIVEN SEDIMENTS (BED-LOAD)显示文摘More than three dozen significant formulae for bed-load transport have been developed over a period of more than 100 years with varying degrees of success. Major problems have been the use of completely or partly empirical approaches and too few data for fitting. This paper presents an analytical formulation for bed-load transport. It is based on a balance of forces for the determination of the thickness of the moving bed-load layer and on the determination of the velocity of this layer. The formula derived is compared to a set of approx. 2000 data published by 32 authors. It is demonstrated that the basic form of the MPM-formula is a special case of the analytical solution. The derivation also includes the effect of bed features such as ripples and dunes on quantitative transport. | Ulrich C. E.
