摘　　要：采用IFA300恒温式HWFA的一维探头对中冷器通道内流场进行了测试研究。测试结果表明:传热边界条件对被测区域的无量纲平均速度的分布影响很小,而传热边界条件不同对湍流度的分布有一定的影响。One-dimensional probes of IFA300 isothermal HWFA were used to measure and study the flow field in the channel of an air-to-air intercooler. The results show that the heat transfer boundary conditions have a small effect on the distribution of non-dimensional mean velocity in the measured field, whereas different heat transfer boundary conditions have a certain effect on the distribution of turbulent intensity.
