摘要

1 引言润滑油在管外环隙间轴向流动时

由于流体粘度大

雷诺数小

一般为层流

光滑管的传热膜系数很低

在本实验范围

Re=300～1000

Pr≈200

油冷却时传热膜系数仅为240～360W/(m~2·℃)。本研究采用花瓣状翅片管强化环隙间润滑油的冷却传热

可有效地扩大传热表面积

并使高粘流体在翅片管三角齿形翅片间轴向绕流到达翅根部

翅间流动死角较小

在本实验范围内

以光坯管面积计的传热膜系数在较好的管参数时可达800～3500W/(m~2·℃)。花瓣状翅片管是对高粘流体较好的一种传热管型。

Abstract

Experimental investigation of heat transfer enhancement of lubricating - oil flowing through the annular space with petal - form fin tube is reported in this paper. Eight kinds of petal - form fin tube are investigated

and the mechanism of heat transfer enhancement with petal - form fins disturbing oil flow is analysed. The results of evaluation of the efficiency of heat transfer enhancement of eight petal - form fin tubes have also been reported.
