Resumen
En esta revisión se describe y se muestra la compleja reología que exhiben las suspensiones concentradas de partículas sólidas no coloidales. Su presencia en la industria y en la vida cotidiana hace que sea relevante describir y explicar el origen de su comportamiento reológico. Para conocer qué son, cómo se comportan, cómo se diferencian de los fluidos Newtonianos y qué estrategias se usan para reproducir su flujo, esta revisión se divide de la siguiente manera: en la sección I se describe la composición y los tipos de suspensiones en función de la fracción de sólidos; en la sección II se describe la reología, que se encarga de caracterizar y describir las propiedades materiales de los fluidos, en este caso, las suspensiones concentradas; en la sección III se exhibe el comportamiento de las suspensiones concentradas, como son: el adelgazamiento al corte, el engrosamiento al corte continuo y discontinuo, y el flujo bandeado en la dirección de la vorticidad; en la sección IV se describen cómo se modelan y cuáles son los mecanismos propuestos que buscan reproducir la reología de las suspensiones concentradas, y en la sección V se muestra el trabajo por hacer en otros tipos de suspensiones.
