1 James Hallendorff Suman Sinha Ray Alexander L. Yarin

2  Investigate instability mechanism in melt blowing

3  Used to measure Lagrangian motion

4

5

6

7  Fast Fourier Transform

8

9  Many harmonics, few that make a difference

10

11  Determine correlation between string length and snapping length or air velocity and snapping length

12  Gravity causes artificial snapping point- makes unreliable results  New setup

13

14

15

16  Using a fixed-length criteria skews results  Compare ratios of width to snapping length

17  Use the frequencies found in the FFT to augment theoretical model  Analyze the movement of the string in a vertical position  Use polymer solution to simulate melt blowing and to compare it to the thread movement model Conclusion: 2 months is not enough
