【摘要】：轉(zhuǎn)沖壓壓縮轉(zhuǎn)子是一種借助激波對(duì)氣體進(jìn)行壓縮新型壓縮系統(tǒng),它集合了超聲速進(jìn)氣道及離心壓氣機(jī)的設(shè)計(jì)方法,通過高速旋轉(zhuǎn)創(chuàng)造相對(duì)超聲速來流的條件,進(jìn)而通過激波對(duì)氣體進(jìn)行壓縮,它具有單級(jí)壓比高、重量輕、體積小等有點(diǎn)。激波系是旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子進(jìn)行壓縮的根本,壓縮面結(jié)構(gòu)是轉(zhuǎn)子激波系結(jié)構(gòu)的決定因素,因此壓縮面設(shè)計(jì)是轉(zhuǎn)子設(shè)計(jì)中至關(guān)重要的環(huán)節(jié)之一。 文章正文主要分成三個(gè)部分： 第一部分介紹了所采用仿真軟件Fluent的特點(diǎn)和優(yōu)勢以及軟件模塊組成和功能意義。并對(duì)所采用的控制方程、差分格式、湍流模型、邊界條件相關(guān)公式進(jìn)了行介紹。 第二部分對(duì)旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子的結(jié)構(gòu)和原理進(jìn)行了分析,對(duì)衡量轉(zhuǎn)子性能的指標(biāo)及其意義進(jìn)行了說明。在此基礎(chǔ)上,對(duì)能對(duì)轉(zhuǎn)子激波系結(jié)構(gòu)有重要影響作用的轉(zhuǎn)子壓縮面進(jìn)行了改型設(shè)計(jì),以凸曲線壓縮面為參考,設(shè)計(jì)了三種能夠產(chǎn)生多條激波的壓縮面。 第三部分首先對(duì)采用凸曲線壓縮面的旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子的流場和性能進(jìn)行了三維全面解析；然后考察了旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子重要的邊界條件背壓變化對(duì)轉(zhuǎn)子性能的影響；最后對(duì)采用不同形式壓縮面的旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子的仿真結(jié)果進(jìn)行詳細(xì)對(duì)比分析,獲得了壓縮面形式影響旋轉(zhuǎn)沖壓壓縮轉(zhuǎn)子性能的一般規(guī)律。
[Abstract]:Rotary press compression rotor is a new compression system for gas compression with shock wave. It integrates the design method of supersonic inlet and centrifugal compressor, and creates the condition of relative supersonic flow through high-speed rotation. Furthermore, the gas is compressed by shock wave, which has the advantages of high single-stage pressure ratio, light weight, small volume and so on. The shock wave system is the basis of compression of rotary compression rotor, and the structure of compression plane is the decisive factor of the structure of the rotor shock wave system. Therefore, the design of compression surface is one of the most important links in rotor design. The text of the article is divided into three parts:. In the first part, the characteristics and advantages of the simulation software Fluent are introduced, as well as the software module composition and functional significance. The equations of control, difference scheme, turbulence model and boundary conditions are introduced. In the second part, the structure and principle of rotary press compression rotor are analyzed, and the index and significance of measuring rotor performance are explained. The compression surface of rotor which has important influence on the structure of rotor shock wave system is modified. Three compression surfaces which can produce multiple shock waves are designed with convex curve compression surface as the reference. In the third part, the flow field and performance of rotary press compression rotor with convex curve compression surface are analyzed, and then the influence of the change of back pressure on rotor performance is investigated. Finally, the simulation results of rotary press compression rotor with different compression surfaces are compared and analyzed in detail, and the general rules of compression surface affecting the performance of rotary stamping compression rotor are obtained.
