Descripción del proyecto
Técnicas eficaces para estudiar materiales en condiciones extremas
La generación de presiones ultraelevadas, comparables a las del núcleo de la Tierra, así como de presiones negativas en líquidos, suele exigir instalaciones únicas y costosas con un acceso bastante limitado. El equipo del proyecto DYNPRESS, financiado con fondos europeos, pretende superar esta limitación. Desarrollará métodos eficaces y asequibles para generar tanto ondas de choque implosivas como ondas de rarefacción, que deberían permitir, respectivamente, estudiar la compresión y la tensión extremas de los líquidos en el entorno cotidiano del laboratorio. Las actividades del proyecto consistirán en desarrollar una instalación que respalde tanto la investigación fundamental como la aplicada.
Objetivo
The project aims at developing robust, reliable and effective techniques for generation of extreme conditions. Positive TPa as well as negative MPa pressures in liquids will be produced with limited resources available in everyday research environment.
The project offers a unique integration of approaches and resources in high voltage engineering and plasma physics applications towards classical problems of compressible fluid mechanics. It investigates by experiment, computation and theory the major physical properties of imploding shock waves in liquids and offers approaches to enhance efficiency of the focal energy concentration. The project develops a novel method for generation of imploding rarefaction waves, a well controlled scenario that provides with exactly opposite range of extreme conditions, namely negative pressures in liquids. The approaches comprise a single generator facility that opens research on a broad spectrum of basic-to-applied subjects, promising a long-term investment towards studies of materials at extremes.
The facility is applied on a selected subject of mechanical treatment of cellulose fibers, aiming at enhancing the efficiency of fibres disintegration, homogenization and fibrillation processes by applying, both selectively and combined, compression and tension pulses on a broad range of intensities, from strong to extreme.
