Research on the Influence of Steam Turbine Seal Leakage
نویسندگان
چکیده
CFD was employed to simulate the steam flow in 1.5-stage cascades with three different seal clearances. When clearance is 0, there no leakage, obvious secondary cascade, and stage efficiency reaches 88.27%. of diaphragm rotor tip 1mm, leakage strongly interferes which promotes formation development end-wall near hub, has little effect on next stage, drops by about 2 percentage points. 4mm, hub stator casing strengthened significantly, attack angle loss increases, so decreases 13

the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Effect of a ring type barrier and rotational speed on leakage flow of gas turbine brush seal
This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...

This paper introduces a kind of diagnosis principle and learning algorithm of steam turbine fault diagnosis which based on Elman neural network. Comparing the results of the Elman neural network and the traditional BP neural network diagnosis, the results shows that Elman neural network is an effective way to improve the learning speed , effectively suppress the minimum defects that the traditi...
