较大流量多支管流量分配实验与数值模拟

Experiments and Numerical Simulation of Flow Distribution with Larger Flux in Multi-branch Pipe

许多烟气加热过程涉及到较大流量多支管流量分配均匀性问题.因此对这类较大流量多支管的流动情况进行了数值模拟和实验研究,得到了分配管内的流动规律及实现流量均匀分配的方法.实验表明,改进分配管结构,可以实现较大流量多支管的流量均匀分配.

Many heating process with smoking gas involves the uniformity problem of flow distribution with larger flux in multi-branch pipe. The authors do the experiments and numerical simulation of flow distribution with larger flux in multi-branch pipe, which gets flow regulation in distributing pipe and the methods to improve flow distribution uniformly. Experiments have shown that improving the frame of distributing pipe may realize the flow distribution uniformly to the pipe with larger flux and multi-branch.
