Аннотация
The paper presents results on heat transfer from a cylinder in pulsating flow. The results are local heat transfer distributions that match four different flow modes identified previously by the authors. A new kind of dimensionless number was introduced for pulsating flows: this is a ratio of flow acceleration during unsteady movement to the centrifugal acceleration due to streamlines bending over the cylinder. The experimental data were generalized as a dependency of the average heat transfer on the new dimensionless criterion. The generalization offered a correction factor to a traditional relation for heat transfer between a cylinder and air flow past the cylinder; this correction takes into account the effect of parameters of forced flow pulsations on the average heat transfer.
