Figure 3.4: Diagram of drop impact outcomes for 9.4mPa s silicone oil drops of radius R = 1.65mm as gas pressure and impact velocity are varied: small-r∗ sheet (red), large-r∗ sheet (blue), and no sheet (white). (Data was not taken below V = 1m s−1, therefore that region is left blank.) The boundaries between the regions are Psmall-r∗ ( ) and Plarge-r∗ ( ). The smaller of the thresholds at a given V determines Psheet (filled symbols). If Psmall-r∗ > Plarge-r∗ , Psmall-r∗ marks the transition between a small-r ∗ and a large-r∗ sheet (empty symbols), as shown in Fig. 3.1. The lines serve as a guide to the eye.
