Resumen
El presente Trabajo Fin de Máster trata sobre la caracterización experimental el movimiento del líquido
cefalorraquídeo (LCR) y del transporte de un soluto en el canal espinal (ESAE), el cual se ha modelado en trabajos
previos. Para ello, se han realizado una serie de experimentos in-vitro, en los que se varían los parámetros clave
del problema (la geometría del canal, el volumen desplazado del canal y la frecuencia de oscilación del
movimiento), cuyos resultados se comparan con los obtenidos a partir del modelo. En dichos experimentos se ha
estudiado la evolución de concentración de un trazador a lo largo del canal espinal y en el cerebro, cuyos
resultados se adecúan a las predicciones del modelo.
The present work consists in an experimental characterization of the cerebrospinal fluid (CSF) motion and the solute transport in the spinal canal (SSAS), which has been modelled in previous works. To that aim, several in-vitro experiments have been conducted, in which the main parameters of the flow (the canal geometry, the tidal CSF volume and the oscillatory flow frequency) have been varied. In these experiments, the evolution of a tracer concentration along the spinal canal and the brain has been studied and their results have been compared with the model then. The experimental results are in good agreement with the model predictions.
