Abstract: Meanders of large amplitude often exhibit asymmetric planform shape or subsidiary bends. The present work is aimed at improving on understanding of the morphodynamic phenomena affecting the bed evolution of large amplitude ...

Abstract: The gradual erosion and transport of fine particles are among the possible consequences to the subsoil of a severe seepage flow, such as the seepage induced by the artificial lowering of the water table by means of pumping ...

Abstract: The features of an axial-symmetric two-dimensional (2D) model in a transient cavitating pipe flow are investigated. A distributed vaporous cavitation model is proposed, based on the mass and momentum balance equations for ...

Abstract: The aim of the paper is to examine nonfriction energy dissipation in transient cavitating flows and to verify whether they can be attributed to thermic exchange between gas bubbles and the surrounding liquid or to gas ...

Abstract: In this paper, the results of an experimental investigation of the turbulence intensity in gravel bed channels are described. The runs were carried out by measuring, with an acoustic Doppler velocimeter, the turbulence ...

Abstract: The numerical analysis of tunnels in rock masses, which exhibit a squeezing behavior, is considered, with reference to the use of two elastoviscoplastic constitutive laws implemented in finite-difference and finite-element ...

Abstract: The goal of this study was to define procedures needed to make a Standardized Reference Evapotranspiration (

Abstract: An entirely numerical design procedure, based on computational fluid dynamics, is introduced to evaluate the performance of different polymer electrolyte fuel cell layouts and sets of operating ...

Abstract: Sediment settling velocities are commonly estimated from analytical or process-based approaches. These approaches have theoretical constraints due to the incompletely resolved settling physics. A parametric data-driven ...
