This chapter describes a new intelligent platform for learning optimal designs of morphing wings based on Variable Camber Continuous Trailing Edge Flaps (VCCTEF) in conjunction with a leading edge flap called the Variable Camber Krueger (VCK). The new platform consists of a Computational Fluid Dynamics (CFD) methodology coupled with a semi-supervised learning methodology. The CFD component of t...

Advances in computer speed and availability of user friendly software has made computational fluid dynamics (CFD) a cost effective compliment and at times alternative to physical modeling in the field of civil engineering hydraulics. The use of CFD is wide spread in mechanical and aerospace engineering, however, in the field of civil engineering and particularly in hydraulics, there is minimal ...

Computational fluid dynamics (CFD) modeling of nominally patient-specific cerebral aneurysms is increasingly being used as a research tool to further understand the development, prognosis, and treatment of brain aneurysms. We have previously developed virtual angiography to indirectly validate CFD-predicted gross flow dynamics against the routinely acquired digital subtraction angiograms. Towar...

We introduce a novel hybrid of two fields-Computational Fluid Dynamics (CFD) and Agent-Based Modeling (ABM)-as a powerful new technique for urban evacuation planning. CFD is a predominant technique for modeling airborne transport of contaminants, while ABM is a powerful approach for modeling social dynamics in populations of adaptive individuals. The hybrid CFD-ABM method is capable of simulati...

Basic research on cerebral aneurysms using computational fluid dynamics (CFD) simulations has recently progressed. We describe a clinical case with the use of CFD simulations. A 76-year-old woman had an unruptured anterior communicating artery aneurysm associated with pseudo-occlusion of the internal carotid artery (ICA). Pre-operative CFD simulations demonstrated that carotid artery stenting (...

A computational fluid dynamics (CFD) code has been combined with a genetic algorithm (GA) to perform a two-dimensional drag minimization on the base region of tractor trailers. Few studies have been conducted with CFD driven by a GA due to extensive run times and the general non autonomous characteristics of meshing a suitable CFD geometry. This study solves the two-dimensional Reynolds-average...

Computational Fluid Dynamics (CFD) has been widely used in pressure drop/hydraulic loss calculations in many industries, including the aerospace and turbo-machinery industry as well as in the nuclear power industry. During the past 30 years, a significant amount of time and effort have been spent in benchmarking the CFD tools and models against test data in aerospace and turbo-machinery industr...
