LDA Experimental Data of Three-Poster Jet Impingement System

Parviz Behrouzi

Volume 1, Issue 1 , October 2004, Pages 1-8

  During its near-ground hovering phase a Short Take-Off and Vertical Landing (STOVL) aircraft creates a complex three-dimensional flow field between jet streams, the airframe surface and the ground. A proper understanding and numerical prediction of this flow is important in the design of such aircraft. ...  Read More

Numerical Investigation of Vortex Interaction in Pipe Flow

Prapat Suntivarakorn; Kazuo Matsuuchi

Volume 1, Issue 1 , October 2004, Pages 9-15

  To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according ...  Read More

Overview of Direct Numerical Simulation of Particle Entrainment in Turbulent Flows

Goodarz Ahmadi

Volume 1, Issue 1 , October 2004, Pages 17-22

  An overview of removal and re-entrainment of particles in turbulent flows is presented. The procedure for the direct numerical simulation (DNS) of the Navier-Stokes equation via a pseudospectral method for simulating the instantaneous fluid velocity field is described. Particle removal mechanisms in ...  Read More

Orbital Perturbation Effect on LEO Satellite Trajectory

Kamran Daneshjou; Aria Alasty; Shahram Rezaei

Volume 1, Issue 1 , October 2004, Pages 23-29

  A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample ...  Read More

Experimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings

G. Atashbaz

Volume 1, Issue 1 , October 2004, Pages 31-39

  It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. ...  Read More
