Optimum Blade Geometry C-9015A to Reduce Blade Erosion
摘要
This paper aims to present the improvement of nozzle blade C-9015A of wet-steam turbines in modern power plants by reducing blade erosion. This may be done with the help of changing the blade's geometry. There are different ways to reduce the erosion of the blade's surface, the most important of which is using special alloys for the blade and coating the nozzle blade. In addition, a new initiative to reduce moisture erosion after moisture hits the blade surface is the use of another function for the geometry of the blade, and the purpose of this paper is to show that under another surface geometry, this surface should have less erosion than itself surface of the geometry of the blade. The impact results of different droplet diameter range on the blade's new geometry have been accounted for and compared with the moisture impact results on the nozzle blade's initial surface. Furthermore, in both cases, the erosion energy on the blade surface has been accounted for and compared.
