چکیده
A new method for measuring surface pressure and shear force based on elastic polymers has been developed. This technique (Surface Stress Sensitive Film, SF) requires extensive data processing, i.e., processing of image pairs into 3D surface deformations and the transformation of these deformations into applied surface forces. This paper describes an analysis method used to determine the 2D lateral surface displacement of SFs. This hybrid method is based on cross-correlation and optical-flow techniques. Test results with synthetic images are reported in this paper. Experimental results with the SF technique using the new analysis algorithms have been obtained in both water and air environments. Results from a low-speed (10 15m/s) vortexgenerator are presented.

11th International Symposium on Flow Visualization
We propose a system that provides interactive denoising, vortex detection, and visualization of vector data. All the major phases of the system are implemented on a GPU (graphics processing unit). Once the vector field has been loaded onto the graphics adapter, no intermediate results need to be read back by the application. By taking advantage of modern GPUs’ parallel processing capabilities, ...
متن کاملVisualization Techniques for the Developing Chicken Heart
We present a geometric surface parameterization algorithm and several visualization techniques adapted to the problem of understanding the 4D peristaltic-like motion of the outflow tract (OFT) in an embryonic chick heart. We illustrated the techniques using data from hearts under normal conditions (four embryos), and hearts in which blood flow conditions are altered through OFT banding (four em...

متن کاملFlow Visualization Around a Non - Circular Tube
The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

We propose a method for visualization of the characteristic feature of complex networks, which displays their static structures, growing processes, and flows on the networks. The method is based on appropriate coloring of edges of network graphs. Applying the method on models of complex networks and some real-world networks, we show several characteristic patterns in many aspects of networks. T...
