| 摘 要： | 本文采用X热线-冷线组合探针,对具有高湍流强度的非等温湍流圆形射流的流场和温度场进行了较精确的测量,尤其是对脉动量及其关联关系的实测和分析不仅在湍流测量方法上具有一定的新意,还为湍流结构、动量与热量交换的类比关系以及相关学科的研究,提供了某些有用的依据.

| Abstract: | A hot X-probe/cold wire arrangement is used for the measurement of flows and temperature fields in a non-isothermal turbulent circular jet. The principal purpose of the present investigation is to obtain reasonably accurate Reynolds shear stress and heat flux distribution and hence a reasonably accurate determination of the turbulent Prandtl number. Not only has a new method of measurement of turbulent flow been developed, but also a useful basis for a study of the turbulence structure, an analogy between momentum transfer and heat transfer etc. is provided by the measurement and analysis of turbulent fluctuating parameters and their correlation terms. |
