This study describes the development, implementation, and evaluation of an effective curriculum for students to learn computational fluid dynamics (CFD) in introductory and intermediate undergraduate and introductory graduate level courses/laboratories. The curriculum is designed for use at different universities with different courses/laboratories,(More)
Simulation technology is integrated into undergraduate engineering courses and laboratories through the development of teaching modules (TM) for complementary computational fluid dynamics (CFD), experimental fluid dynamics (EFD), and uncertainty analysis (UA). TM include three parts: (1) lectures on CFD and EFD methodology and standard procedures and UA;(More)
The recent development of CFDShip-Iowa Version 6, a high-performance, high-fidelity Cartesian grid solver for computational ship hydrodynamics, is presented. First, a wall function approach has been introduced for wall-layer modeling based on the immersed boundary method and the one-equation Spalart-Allmaras turbulence model. Second, in order to develop(More)
In this paper, we present a combined immersed-boundary/ghost-fluid sharp interface method for the simulations of three-dimensional two-phase flows interacting with moving bodies on fixed Cartesian grids. This work is based on a sharp interface immersed boundary method for fluid flows interacting with moving bodies 32 and a level set based ghost fluid method(More)
This effort is focused on hydrodynamic shape optimization with application to naval vehicles. At present, this is mainly applied to US Navy surface combatant hull forms and related systems; however, this approach could also be applied to other marine applications. In addition, this effort is aimed at assessing the current use of hydrodynamic analysis tools(More)
