Visualization of Supersonic Flow Using Computer Image Processing Technique.

Detection of Coastline Using Satellite Image-Processing Technique

Extended abstract 1- Introduction  Coasts maintain their natural sustainability without human intervention and in spite of short-term changes, we are ultimately confronted with a coastal healthy environment, i.e. natural, rocky beaches, sandy beaches and so on. Today's use of remote sensing in most natural sciences is widespread. Due to the fact that fieldwork is costly and time-consuming, ...

Supersonic Combustion Flow Visualization at Hypersonic Flow

Currently, a new generation of scientific aerospace vehicles, using advanced hypersonic airbreathing propulsion based on supersonic combustion technology, is in development at several research centers [1]. The 14-X Brazilian Hypersonic Aerospace Vehicle, Figure 1, designed by Rolim et al. [2], at the Prof. Henry T. Nagamatsu Laboratory of Aerothermodynamics and Hypersonics, Figure 2, at the Ins...

Modeling & Simulation of Supersonic Flow Using McCormack’s Technique

In this work, two-dimensional inviscid supersonic flow around a wedge has been investigated using CFD scheme. The employed scheme is McCormack’s predictor-corrector scheme. Our own code, CFMOD was written using MATLAB environment. Proper boundary conditions and the grid parameters were decided on the basis of standard techniques. The results are verified using classic theories for supersonic fl...

Flow Visualization of Angled Supersonic Jets into a Supersonic Cross Flow

This paper describes Nano-particle based Planar Laser Scattering (NPLS) flow visualization of angled supersonic jets into a supersonic cross flow based on the HYpersonic Low TEmperature (HYLTE) nozzle which was widely used in DF chemical laser. In order to investigate the non-reacting flowfield in the HYLTE nozzle, a testing section with windows was designed and manufactured. The impact of seco...
