Smoke Visualization and Hot Wire Measurements of Three Dimensional Separated Flows.

Three Dimensional Modeling of Hot Jupiter Atmospheric Flows

We present a three dimensional hot Jupiter model, extending from 200 bar to 1 mbar, using the Intermediate General Circulation Model from the University of Reading. Our horizontal spectral resolution is T31 (equivalent to a grid of 48×96), with 33 logarithmically spaced vertical levels. A simplified (Newtonian) scheme is employed for the radiative forcing. We adopt a physical set up nearly iden...

Hot-Wire Attenuation and Its Correction in Turbulence Measurements

A scheme is proposed for correcting the hot-wire attenuation in turbulence measurements in both frequency and time domains. The scheme is tested for simulated hot-wire signals under velocity impulse and sinusoidal perturbations of various frequencies. It is found that the frequency response of the hotwire system and the calculated central moments, after applying the correction, can be greatly i...

Three-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter

In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

Visualization of three-dimensional incompressible flows by quasi-two-dimensional divergence-free projections

Context: A visualization of three-dimensional incompressible flows by divergence-free quasitwo-dimensional projections of velocity field on three coordinate planes is proposed. Objective: To visualize 3D incompressible flow by 3 two-dimensional plots. Method: It is argued that such divergence-free projections satisfying all the velocity boundary conditions are unique for a given velocity field....
