Title: S0501-2-2 Molecular Dynamics Simulation of Effects of Electric Field Strength and Temperature on Nematic Liquid Crystalline Flow

Under the application of electric fields, transient velocity fields are generated as the result of molecular reorientation. The magnitude of velocities and the time required for the development of the velocity fields depend on the strength of electric fields and temperature. With the increase in electric field strength, the magnitude of velocity increases and the time to reach the maximum velocity becomes shorter. With the increase in temperature, the kinetic energy of molecules becomes more dominant than the potential energy such that the resistant to the bulk reorientation by the electric field becomes smaller. As the consequence, under the same electric field strength, the magnitude of velocity increases and the time to reach maximum velocity decreases with the increase in temperature.Read More
