Computational Aerodynamics and Fluid Dynamics: An Introduction

Using Computational Fluid Dynamics for Aerodynamics

In this white paper we survey the use of computational simulation for aerodynamics, focusing on applications in Aerospace and Turbomachinery. We present some representative problems to illustrate the range of complexity in fluid simulations and the associated computational requirements. We also examine the design process in current industrial practice, and the role played by computational fluid...

Unsteady computational fluid dynamics modeling of free-flight projectile aerodynamics

This paper describes a new multidisciplinary computational study undertaken to model the flight trajectories and the free-flight aerodynamics of both a finned projectile at supersonic velocities and a spinning projectile at subsonic speeds with and without aerodynamic flow-control. Actual flight trajectories are computed using an advanced coupled computational fluid dynamics (CFD)/rigid body dy...

Investigation of Cavity Flow Aerodynamics Using Computational Fluid Dynamics

The acoustic environment of a bomb bay or cavity causes large pressure oscillations and the severity of them is a problem that has intrigued researchers for years [68]. Many suppression techniques have been applied with varying degrees of success. Despite this, the understanding of why the pressure oscillations exist or how the suppression methods work have not been investigated as thoroughly. ...

An introduction to computational fluid dynamics - the finite volume method

Computational Fluid Dynamics using OpenCL – a Practical Introduction

The main aim of the Computational Fluid Dynamics (CFD) simulations is to reconstruct the reality of fluid motion and behaviour as accurately as possible in order to better understand the natural phenomena under specified conditions. Ideally, general solutions can also cover different scales and geometric configurations. Unfortunately, due to expensive algorithms, classic CFD codes most often re...
