The caloric curve in collisions

Mostrar todas las versiones(2)

We study the relationship between the excitation energy absorbed in collisions of drops and the temperature achieved. We investigate central collisions of two-dimensional Lennard-Jones droplets of size 3 impacting on size 100 "nuclei" using micro canonical molecular dynamics techniques. We...
