“…Many authors (Fiala et al 2001;Gerlach et al 2008;Jaeger et al 2009;Lindgren et al 2002;van den Bosch et al 2002) have described the temperature distribution in a PEF treatment chamber and reported the occurrence of high local temperatures due to the inhomogeneous distribution of the electric field, limited flow velocity, and recirculation of the liquid. Numerical simulations using computational fluid dynamics have attracted increased interest for this purpose since experimental measurement of the related parameters is not possible in most cases due to the small dimensions of the treatment chamber as well as the interference of the measuring device with the product flow and electric field.…”

“…Esto ha de ser tenido en cuenta al definir las condiciones de procesado, ya que hay que garantizar que todo el alimento recibe el tratamiento mı´nimo adecuado (Meneses et al, 2011). Atendiendo a ello, en la u´ltima de´cada se ha generalizado el uso de me´todos nume´ricos de simulacio´n para mejorar el disen˜o de este tipo de ca´maras, tendiendo en cuenta tanto la distribucio´n del campo ele´ctrico y la temperatura como las caracterı´sticas del flujo de producto (Buckow, Schroeder, Berres, Baumann, & Knoerzer, 2010;Fiala, Wouters, van den Bosch, & Creyghton, 2001;Gerlach et al, 2008;Jaeger, Meneses, & Knorr, 2009;Lindgren, Aronsson, Galt, & Ohlsson, 2002).…”

“…The first is proper design and shaping of electrodes to eliminate field inhomogeneities and regions of excessive high field strength significantly (Fiala et al, 2001). Secondly, the appearance of air bubbles should be suppressed by applying a static backing pressure (Fig.…”
