一种船用压差控制喷嘴的改进设计

摘要

In order to adapting the ship's environment,the improvemental design of the Venturi nozzle was made by simplifying the line type and shortening the length.The CFD software was used to get the flow and pressure data in each working condition to verify the design.Experiments were carried out by a test platform,showing that the new improved nozzle's indicators meet the requirements of pressure difference control.%为适应船舶的安装环境,对文丘里喷嘴进行改进设计,简化型线,缩短长度,利用CFD软件进行仿真模拟,各工况下的流量和压差数据初步验证了设计的正确性,搭建试验平台,试验结果表明,改进后喷嘴的各项指标能够满足压差控制的技术要求.
