چکیده انگلیسی
The behaviour of nano-scale jets emanating from a reservoir under the action of an external force is studied using Langevin dynamics simulations. The advantage of employing a Langevin thermostat to maintain the temperature of the fluid reservoir is highlighted. The effect of hydrodynamic screening introduced by the Langevin thermostat is considered. It is seen that the nature of thermostat plays a crucial role in simulating the onset of instabilities in the liquid structures. A plunger action has been chosen to initiate jet generation. Langevin dynamics is seen to be able to model the physics of nano-scale jets quite accurately. The study also shows that the Langevin dynamics simulations are capable of capturing the dynamics of nano-scale liquid jets, as the nanojet simulated by this method is found to behave in close agreement with the theoretical predictions for nano-scale jets.
