The role of polydispersity in the mechanism of drag reduction
The effects of polydispersity in drag reduction were studied by testing two narrow molecular weight distribution polystyrene samples individually and in mixtures. The results indicate that the largest molecules in the distribution determine the value of the onset point and that this value decreases...

| description | The effects of polydispersity in drag reduction were studied by testing two narrow molecular weight distribution polystyrene samples individually and in mixtures. The results indicate that the largest molecules in the distribution determine the value of the onset point and that this value decreases with increasing molecular weight. Above the onset point the magnitude of the drag reduction effect is shown to be a complex function of both molecular weight and polydispersity. |
