Concretamente, estos sistemas se segregan en dominios de las diferentes especies obteni\u00e9ndose comportamientos cin\u00e9ticos an\u00f3malos.  estudiamos estos comportamientos no formales en el sistema reactivo binario a+b=o mediante la explotaci\u00f3n anal\u00edtica y num\u00e9rica de las ecuaciones deterministas de reacci\u00f3n-difusi\u00f3n para las concentraciones locales de ambos reactivos suponiendo v\u00e1lida la aproximaci\u00f3n de campo medio para el t\u00e9rmino de reacci\u00f3n.  en una segunda parte del trabajo se ha incorporado al modelo un tercer proceso, el de mezcla, con el que intentamos homogeneizar el sistema y recuperar el comportamiento cin\u00e9tico cl\u00e1sico. Trabajamos principalmente con dos flujos hidrodin\u00e1micos bidimensionales, el de red de remolinos y el turbulento.  si bien en ambos casos a tiempos intermedios recuperamos la conducta cl\u00e1sica, a tiempos suficientemente grandes con sonseguimos evitar la segregaci\u00f3n del sistema.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Effects of
