Radar Imagery : Looking from Space with Wavelengths 100000 Times Larger than the Ones of Visible Light
Radar instruments are used to observe the Earth with radio waves. The resulting image reflects both the physical properties of the waves and the technological choices that have to be made to obtain a usable image from the raw data gathered by the ...
Pressure Distribution on a Roof in Presence of the Moving Surface Boundary-layer Control
The paper studies effect of momentum injection, accomplished through circular cylindrical rotating elements, on the pressure distribution at the roof of a model house. Extensive wind tunnel tests, complemented by flow visualization, suggest that such ...
A Study of Pulsatile Jet Discharged from Pipe End
Noise is generated from a flow field upstream of a shock wave periodically discharged from a pipe end. A vortex ring and an underexpanded jet are periodically formed and diffused downstream. To clarify the mechanism of the noise generation, the flow ...
Vortex Structures and Temperature Fluctuations in a Bluff-body Burner
Vortical and thermal structures of non-premixed propane flame in a bluff-body burner are studied experimentally in the transition from laminar to turbulent flow. In particular, we focus attention on the effect of annular air flow on the flame. The small-...
Flow Visualization for an Unconventional Forebody
Some results of flow visualization are described for an unconventional fuselage with Erickson-like forebody. The experiment includes force measurement, surface oil flow visualization, and laser sheet flow visualization. Some results are also obtained ...
Three-dimensional Bubbly Flow Measurement Using PIV
The experimental flow visualization tool, Particle Image Velocimetry (PIV), is being extended to determine the velocity fields in three-dimensional, two-phase fluid flows. In the past few years, the technique has attracted quite a lot of interest. PIV ...
3-D Airflow Measurement Using Smoke Particles
A new 3-D PIV-technique that is applicable to low velocity airflow in a real space such as indoor airflow is proposed, and its performance is inspected through a simulation and an experimental application. In this technique, two parallel planes ...
A Study on Particle Identification in PTV Particle Mask Correlation Method
An algorithm for particle identification in PTV, which is classified in the category .particle mask correlation method,.is presented and tested. A typical brightness pattern of a particle image is referred to as a particle mask. The particle mask is ...
Summary of FLUCOME '97 Hayama: Report
This article is a summary of the fifth Triennial International Symposium on Fluid Control, Measurement and Visualization, FLUCOME '97 Hayama, which was held from September 1 to September 4 in 1997 at Hayama, Japan. The FLUCOME symposium was held at ...
