Descripción del proyecto
Los materiales «rebeldes» ceden al ímpetu de jóvenes investigadores motivados
Por lo general, la mayoría de las personas no consideran que materiales como la pasta de dientes, la mayonesa, el cemento y el barro sean fluidos. Con todo, en el ámbito de la ciencia de los materiales, estos materiales se denominan «fluidos de límite elástico», esto es, solo «fluyen» si se ejerce sobre ellos una tensión de corte suficientemente grande que hace que cedan y comiencen a fluir en lugar de deformarse elásticamente. La comprensión de los fluidos de límite elástico es fundamental para sectores tradicionales, como el procesamiento de alimentos y la construcción, y está creciendo en consonancia con el desarrollo de nuevas tecnologías, como la impresión 3D. Con todo, a pesar de su ubicuidad e importancia, las teorías actuales que describen sus características de flujo solo son válidas en condiciones muy básicas y su estudio experimental sigue siendo bastante complejo. YIELDGAP está creando una red de formación innovadora que aúna a expertos del mundo académico y el sector industrial y a jóvenes investigadores brillantes para mejorar los modelos y métodos experimentales en el ámbito de los fluidos de límite elástico.
Objetivo
Industries based on yield-stress fluids are rapidly expanding in Europe, including key traditional sectors (food, building,
paper) and key emerging technologies (advanced materials, advanced manufacturing). The European Parliament has called
for investment on these sectors, but so far complex fluid processes in these industries are far from understood, as the
research
has generally been small scale and/or technologically flawed. In particular: the poor understanding of yield-stress
fluid rheology and linking of the measured parameters to the yield properties and insufficient models, means that
applications are designed without the understanding of even the basic flow properties (no-flow zones, pressure needed to
initiate flow), which introduces uncertainties and errors; there is a serious shortage of research trained professionals who
combine expertise on complex fluid research, technology and industrial needs. In conjunction with ESR the largest network
in Europe in rheology, this ITN will: develop a European multi-disciplinary, intersectoral educational research framework for
Europe, to comprehensively train 12 early stage researchers (ESRs) to PhD level; provide the research evidence to show
how modern measurement and modelling methods may improve the cost- and resource-efficiency of industrial processes;
provide the European workforce with a much needed new generation of excellent research trained professionals. The
scientific objectives of YIELDGAP covered by the 4 research workpackages are to: establish advanced and highly improved
numerical modelling tools of complex fluids including additives; validate models by lab and field measurements; integrate
measured fluid properties with model parameters; build and disseminate best practices for industry and academia. Using
advanced methods where the YIELDGAP partners are world leading, the work of this ITN will culminate in international
consensus guidelines for yield-stress fluid flow measurement and prediction.
