The transition of the vibration mode of an evaporating drop of liquid nitrogenplaced on a horizontal surface at room temperature is investigated by image analysisand model simulation. The vibration mode is indicated by the number of waves n ap-pearing along the periphery. In this paper, images of the drc>p in 16 mm film madeduring the transition from the n=5 mode to the n=3 mode are processed. From theimages of the instantaneous plane shapes, nonlinear interaction between severalmodes and random behavior are identified durirtg the transition. A simple modelanalysis is created to simulate this transition process. Results of the model analysisagree with the observation, and suggest a dependettce of the transition mechanism onthe degree of thermal inequilibrium.
