| 摘 要： | 对水横掠热柱体时旋涡脱落时的流动试验进行了分析.研究表明,考虑热效应后的旋涡脱落发生明显变化,表现在旋涡脱落信号傅里叶变换峰宽的改变.在一般换热器设计中往往忽略了壁面热效应,应引起有关部门注意. |
| 关 键 词： | 旋涡脱落 傅里叶变换 加热柱体 绕流 |

| Abstract: | The vortex shedding characteristic on heated circular cylinder in water cross flow is examined experimentally in this paper.It is showed that allowing for heat effect,spectrum width of vortex shedding signal experiences considerable changes.But,heat effect of cylinder is ignored commonly, thus should be regarded by the designer. |
| Keywords: | vortex shedding Fourier-transform heated cylinder cross flow |
