Dielectric fluid in inhomogeneous pulsed electric field

Pulsed Electric Field Processing in Food Technology

Pulsed electric field (PEF) processing is a emerging method of food preservation that uses short bursts of electricity for microbial inactivation (cell-lysis) and causes minimal or no detrimental effect on food quality attributes. PEF can be used for processing liquid and semiliquid food products.

Electric-field fluctuations in random dielectric composites

When a composite is subjected to a constant applied electric, thermal, or stress field, the associated local fields exhibit strong spatial fluctuations. In this paper, we evaluate the distribution of the local electric field ~i.e., all moments of the field! for continuum ~off-lattice! models of random dielectric composites. The local electric field in the composite is calculated by solving the ...

Pulsed light and pulsed electric field for foods and eggs.

Two new technologies for use in the food industry are described. The first method discussed uses intense pulse of light. This pulsed light (PureBright) process uses short duration flashes of broad spectrum "white" light to kill all exposed microorganisms, including vegetative bacteria, microbial and fungal spores, viruses, and protozoan oocysts. Each pulse, or flash, of light lasts only a few h...

Study of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios

In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...
