the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...

In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...

Uintah is a computational framework for fluid-structure interaction problems using a combination of adaptive mesh refinement(AMR) and MPM particle methods. Uintah uses domain decomposition and a task graph based approach for asynchronous communication and automatic message combination . The original task scheduler for Uintah ran computational tasks in a predefined order. To improve the performa...
