Flow visualization with stereo shadowgraphs of stratified fluid.
Water stratified thermally or with dissolved material has a refractive index that varies with height. The stratification has no obvious visual effect until the fluid is disturbed, for example by a fish, but then it marks the creature's wake with a jump in refractive index that is visible in shadowgraphic projection. Two shadowgraphs in stereo display the wake in three dimensions. For a permanen...
متن کاملFluid Flow Visualization
This paper presents an overview of techniques for visualization of fluid flow data. As a starting point, a brief introduction to experimental flow visualization is given. The rest of the paper concentrates on computer graphics flow visualization. A pipeline model of the flow visualization process is used as a basis for presentation. Conceptually, this process centres around visualization mappin...
متن کاملTeaching Fluid Mechanics with Flow Visualization Videos
This paper describes a new series of 10-15 minute narrated videos that use flow visualization to illustrate basic fluid mechanics concepts. These videos are distributed in DVD form accompanying a basic fluids textbook. Fluid mechanics is fundamentally visual, and visual topics can be taught by modern multimedia methods. Our philosophy of thus providing a “glimpse through the research laboratory...
متن کاملLinear Inviscid Damping for Couette Flow in Stratified Fluid
We study the inviscid damping of Couette flow with an exponentially stratified density. The optimal decay rates of the velocity field and the density are obtained for general perturbations with minimal regularity. For Boussinesq approximation model, the decay rates we get are consistent with the previous results in the literature. We also study the decay rates for the full Euler equations of st...
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...
