Computational Fluid Dynamics (CFD) is a fundamental step for the study and optimization of electricity production. Indeed, current power plants use water as a mean of convective heat transfer. Consequently, the simulation, analysis and visualization of fluid dynamics phenomena are of great importance for the energy industry. Electricite de France (EDF), being one of the biggest electricity prod...

Air flow through electric fan heater channel is governed by coupled, non-linear partial differential equations; these equations have to be solved within on irregular domain subject to various initial and boundary conditions. Computational Fluid Dynamics (CFD) replaces fluid flow equations by a set of algebraic equations, these algebraic equations can be solved using digital computers. Wall to a...

Over the past 30 years, numerical methods and simulation tools for fluid dynamic problems have advanced as a new discipline, namely, computational fluid dynamics (CFD). Although a wide spectrum of flow regimes are encountered in many areas of science and engineering, simulation of compressible flow has been the major driver for developing computational algorithms and tools. This is probably due...

Plunging wave breaking is of great importance to ship hydrodynamics, including strong turbulence with large amounts of air entrainment, bubbles, droplets, jets, and spray. Previous experimental fluid dynamics (EFD) and computational fluid dynamics (CFD) studies on plunging wave breaking are mainly focused on the global structures of the wave breaking, such as wave elevation, jet, air cavity, an...

1. Abstract Nowadays, the use of computational fluid dynamics (CFD) in the design of valves is very common. Despite the continuing growth of computing capability, the computational cost of complex three-dimensional CFD analysis of butterfly valve maintains high, therefore, the CFD analysis-based optimization becomes more time-consuming and computational expensive. In this paper, a comparative s...

A multi-objective optimization (MOO) of two-element wing models with morphing flap by using computational fluid dynamics (CFD) techniques, artificial neural networks (ANN), and non-dominated sorting genetic algorithms (NSGA II), is performed in this paper. At first, the domain is solved numerically in various two-element wing models with morphing flap using CFD techniques and lift (L) and drag ...

It is necessary to obtain a fundamental understanding of the goaf gas flow patterns in longwall mine in order to develop optimum goaf gas drainage and spontaneous combustion (sponcom) management strategies. The best ventilation layout for a longwall underground mine should assist in goaf gas drainage and further reduce the risk of sponcom in the goaf. Further, in the longwall panel, regulators ...

Introduction: Knowledge of blood flow patterns in the human body is a critical component in cardiovascular disease diagnosis. In-vivo blood flow is typically assessed either by 3D phase-contrast MRI [1], or by Computational Fluid Dynamics (CFD) calculations [2]. MRI measurements are direct, but offer limited spatio-temporal resolution. Conventional CFD calculations offer "infinite" spatial reso...
