Computational analysis of Newtonian fluid in a 2-D square cavity with kinetic energy, enstrophy, and palinstrophy in the presence of bottom corner obstacle
Published 2025-01-01“…Understanding the impact of obstacles on lid-driven cavity (LDC) flows is critical for advancing flow control and optimization in fluid dynamics. In this study, we numerically investigate steady, two-dimensional Newtonian fluid flow within a square cavity featuring a lid-driven motion at Reynolds number Re = 100 by solving governing equations with the Fractional Step Method on a staggered grid in the Finite Volume framework, providing high-resolution streamline plots and vorticity contours. …”

Optimal Paths on Urban Networks Using Travelling Times Prevision
Published 2012-01-01“…We deal with an algorithm that, once origin and destination are fixed, individuates the route that permits to reach the destination in the shortest time, respecting an assigned maximal travel time, and with risks measure below a given threshold. A fluid dynamic model for road networks, according to initial car densities on roads and traffic coefficients at junctions, forecasts the future traffic evolution, giving dynamical weights to a constrained 𝐾 shortest path algorithm. …”
