• Investigate instability mechanism in melt blowing

• Used to measure Lagrangian motion

• Fast Fourier Transform

• Many harmonics, few that make a difference

• Determine correlation between string length and snapping length or air velocity and snapping length

• Gravity causes artificial snapping point-makes unreliable results

• New setup

• Using a fixed-length criteria skews results

• Compare ratios of width to snapping length

• 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 modelConclusion: 2 months is not enough
