本文对轴流式涡轮排气道的气动性能及吹风试验结果进行了分析。从一系列的试验结果中可以看出,在涡轮排气道中采用轴径向式扩压器来组织气流,可以明显降低排气道的损失。本文还就在增压器上应用轴径向式扩压器的情况作了介绍。这一研究成果有一定的实用价值,特别是在涡轮排气壳结构不变的前提下,在排气壳内加装合适的扩压器即可提高增压器效率,这为使用中的增压器的技术改造提供了依据。
In this paper, the aerodynamic performance of the axial turbine exhaust duct and the results of the blowing test are analyzed. From a series of test results, it can be seen that the axial radial diffuser is used to organize the air flow in the turbine exhaust duct, which can obviously reduce the exhaust duct loss. This article also describes the use of a shaft radial diffuser on a turbocharger. This research results have some practical value, especially in the turbine exhaust shell under the premise of the same, in the exhaust shell can be installed with a suitable diffuser turbocharger efficiency can be increased, which is used in the increase Pressure converter provides the basis for technological innovation.
