  wall angle
The impact on side-wall angle, aspect ratio, and shape of the bottom of the etched structures is discussed.
      
Shock waves impinging on axisymmetric converging passages of moderate wall angle undergo cyclical Mach reflection processes which are generally not self-similar during progression through the contraction.
      
Mach reflection is maintained as the dominant reflection process throughout this range but the number of cycles decreases as wall angle increases.
      
A wall angle of better than 87o is preferred, and optimization of the etch process will be a subject for future investigation.
      
By varying the aft wall angle, the offset ratio of upstream to downstream depth and the cavity length the following main results were found.

As a resuit of its small tube diameter and the multiplicity of the mixing stages, the UP boiler manufactured by Shanghai Boiler Works is unsuitable for cycling load and sliding pressure operation. Moreover, the perimeter of the furnace is constrained by the mass flow rate in the waterwall; consequently the range of coals that can be successfully burnt are also limited. With a view to solving the above problem, the improvement of the UP boiler, especially the possibility of using variable pitch waterwall for sliding pressure operation based on the calculation of the effectiveness factor for furnace wall area, is explored in this article. The merits and shortcomings of variable pitch waterwall also discussed.

上海锅炉厂生产的UP炉由于管径细,混合级数多,不适合带中间负荷滑压运行。且炉膛周界受水冷壁重量流速的限制,使其对煤种的适应性亦受到限制。鉴于上述问题,本文就UP炉的改进问题,从炉膛水冷壁角系数的计算分析开始,探讨UP炉采用变节距水冷壁对于滑压运行的可能性。论述了变节距水冷壁可能存在的优缺点。
