摘要: A colloidal fluid is found to rotate spontaneously during electrolysis when gravity acts perpendicular the direction of an applied electric field. An aqueous dispersion containing charged particles placed inside O-ring sandwiched between two parallel ITO electrodes. clip used hold assembly together prevent liquid from leaking out. The positioned such that electrodes stand vertically, i.e., field points gravity. When a direct-current voltage initiate water, nonlinear pattern formed by electroconvective flow. Moreover, entire rotates about center with constant angular velocity. rotational dynamics are governed how strong and where clipped relative gravitational direction. new phenomenological relationship velocity, compression vector, derived. Coupling of...
