Elevation of the temperature of liquid films caused by rapid rupturing

Although there have been several experimental and numerical works on rapidly rupturing films, measurement of the spatial-temporal temperature during rupturing processes is lacking. Using molecular dynamics simulations, we show that a rupturing film with nanometer thickness generates a non-negligible temperature increase. We demonstrate a correlation between the rupture velocity, the temperature increase, and the initial film thickness. Our findings show that the temperature increase causes changes to the physical properties, which affect the film-rupturing behavior.
