摘要

采用ANSYS有限元通用软件

对设计开发的圆环主半径54 mm、圆柱高180 mm、横向圆柱长45 mm、冷却水初始温度320 K、冷却器内壁温度525 K的内冷却器-U形管内冷却水速度为6～14 m/s时

对流场温度场耦合作用下冷却水流动状况进行数值模拟。结果表明

进口速度太小

易在弯曲区形成涡流

速度太大

易在弯曲区产生更大的流速

对管壁冲击较大

影响其使用寿命;所以内冷却器进口速度在10 m/s时冷却效果最佳。

Abstract

Numerical simulation of flow status of cooling water with flow rate 6～14 m/s in the developed inner U- shape cooling pipe with main radius 54 mm

column height 180 mm

transverse column length 45 mm

cooling water initial temperature 320 K and cooler inner wall temperature 525 K in coupling action of flow field and temperature field has been caried out by an ANSYS finite element software.Results indicated that with lower inlet flow rate

the eddy current easily produced in curved region

with higher inlet flow rate

the higher flow rate produced in curved region to impact the inner wall and decrease its service life.The inner cooler inlet flow rate for optimum cooling effect was 10 m/s.
