This study evaluated the effects of dielectric barrier discharge (DBD) plasma technology on some physicochemical and structural properties corn starch. Amylose content, solubility, water absorption index, turbidity, relationships, surface morphology were measured at 100, 200, 300 Hz excitation frequencies 10 20 min exposure times. The treatment 200 promoted most significant modifications in amy...

Abstract A numerical algorithm is proposed for simulation of the dielectric barrier discharge plasma actuators including photo-ionization. The computational bottleneck related to a very long computing time has been circumvented by suppressing pulses and proposing mean model. It incorporates an artificial damping term into electron transport equation suppress formation pulses, which significantl...

A self-consistent two-dimensional fluid model is employed to investigate the coaxial–coplanar dielectric-barrier discharge (DBD) excited by sinusoidal voltage in atmospheric helium. Simulation results show that there are two current pulses positive half cycle, but only one negative cycle. The transformed from Townsend-like mode, through glow-like and back mode both cycles, during which electric...
