摘    要:燃烧室迷宫复合冷却结构是一种集冲击、对流换热和近似发散冷却于一身,兼具冲击冷却、对流换热冷却和席壁冷却结构优点的创新性冷却结构。本文在研究该结构冷却机理的基础上,从实用的角度出发,以某型现役发动机燃烧室改型设计为例,对瓦块式迷宫冷却结构进行设计,并进行换热分析和壁温计算。初步研究表明,该冷却结构的冷却性能优于全气膜冷却结构。

关 键 词:瓦块  迷宫复合冷却结构  换热分析  冷却性能

Abstract:Maze composition cooling structure of combustor is a kind of novel cooling structure incorporated the strong points of impingement, convection heat exchange and approximately perspiration cooling. It possesses the advantages of impingement, convection heat exchange and mat wall cooling structure, so it is an ideal cooling structure. On the basis of investigating cooling mechanism of this cooling structure and from the practical point of view, tile maze cooling structure is designed by taking the modification design of combustor in active service engine for example. Meantime heat exchange analysis and calculation of wall temperature also are made. Preliminary investigation shows that the cooling performance of this cooling structure is superior to that of full air - film cooling structure.
Keywords:tile  maze composition cooling structure  analysis of heat exchange  cooling performance
