ABSTRACT CTS-9418973 Morteza Gharib Detailed measurements of three-dimensional velocity, vorticity, and temperature fields in the wake behind a circular cylinder will be carried out using novel high-resolution techniques; these measurements will be related to the mean global properties of the cylinder (heat transfer coefficient, for example); and provide information for comparison with numerical models of flow and heat transfer in the same geometry being performed concurrently by another investigator. The comparison will provide needed validation (or invalidation) of the accuracy of contemporary numerical predictive techniques.

CTS-9418973 Morteza Gharib将使用新的高分辨率技术对圆柱体后尾迹的三维速度、涡量和温度场进行详细测量；这些测量将与圆柱体的平均整体性质(例如，换热系数)有关；并提供信息，以与另一研究人员同时进行的相同几何形状的流动和换热的数值模型进行比较。这种比较将为当代数值预测技术的准确性提供必要的验证(或失效)。
