Analysis of Cold Flowfield of Multi-Annular Opposed Jets

Journal of Thermal Science 1992年第2期1卷 135-139页

The technique of the use of multi-annular opposed jets as different from using swirl and bluff body creates an excellent recirculation zone with desired size in a large *** size of ecirculation,the magnitude of reverse velocity and turbulence intensity are much greater than those formed by bluff *** affecting the flowfield include the velocity ration of the opposed jets to the primary air *** diameter and construction of the opposed jet ring,secondary air velocity and configuration,and confined or unconfined flow condition and so *** method is a promising way for flame stabilization in combustion technology.

A methodological approach for estimating turbidity in a river

During the operations of purging and disposal of sediments of a reservoir it is necessary to know the values of turbidity in the river downstream in natural condition,in the absence of dams or river training *** paper shows that under these conditions the ratio of the average values of sediment discharge to the annual maximum value of water discharge is a function of the average annual *** can be considered as representative synthetic index of the climatic conditions,the lithological features and the land cover of the basin,and the geometric characteristics of the river *** proposed relationship of sediment discharge as a function of water discharge were validated on the basis of data collected from different Italian regions that have very different morphological,geo-lithological and rainfall features and that are characterised by a basin area changing between a few dozen and thousands of square *** results can be considered satisfying.
