No full textThis work deals with the recharging-dewatering problem for an unconfined aquifer. In particular, the evolution of the aquifer free surface consequent to changes in the water level in a trench near the aquifer itself has been investigated. The problem has been analyzed using a numerical approach so as not to eliminate the nonlinearities of the boundary conditions: the Laplace equation has been solved using the finite-element method coupled to an interpolation-collocation method for the solution of the free surface kinematic condition. Many configurations, which are most likely to cover cases of practical interest, have been studied, and the results have been summarized in a simple formula that permits the evaluation of the aquifer portion that is affected by recharging-dewatering action
A review of multiscale 0D–1D computational modeling of coronary circulation with applications to cardiac arrhythmias
Full text linkComputational hemodynamics is becoming an increasingly important tool in clinical applications and surgical procedures involving the cardiovascular system. Aim of this review is to provide a compact summary of state of the art 0D–1D multiscale models of the arterial coronary system, with particular attention to applications related to cardiac arrhythmias, whose effects on the coronary circulation remain so far poorly understood. The focus on 0D–1D models only is motivated by the competitive computational cost, the reliability of the outcomes for the whole cardiovascular system, and the ability to directly account for cardiac arrhythmias. The analyzed studies show that cardiac arrhythmias by their own are able to promote significant alterations of the coronary hemodynamics, with a worse scenario as the mean heart rate (HR) increases. The present review can stimulate future investigation, both in computational and clinical research, devoted to the hemodynamic effects induced by cardiac arrhythmias on the coronary circulation
