FLOW VISUALIZATION ON CONICAL VORTEX ON A FLAT ROOF

Effect of plasma actuation on asymmetric vortex flow over a slender conical forebody

The active flow control technology by using plasma actuation to manipulate forebody vortices on a slender conical body is being studied based on the previous research. This work is motivated by the need to increase the experimental velocity in the wind tunnel via an effective streamlining created by the actuators. A pair of Single-Dielectric Barrier Discharge (SDBD) plasma actuators is installe...

Flow 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...

Conical Distributions on the Space of Flat Horocycles

Let G0 = K ⋉ p be the Cartan motion group associated with a noncompact semisimple Riemannian symmetric pair (G, K). Let a be a maximal abelian subspace of p and let p = a+ q be the corresponding orthogonal decomposition. A flat horocycle in p is a G0-translate of q. A conical distribution on the space Ξ0 of flat horocycles is an eigendistribution of the algebra D(Ξ0) of G0-invariant differentia...

Flow Routing on Flat Terrains

Most current flow routing algorithms use digital elevation models (DEMs) to construct flow models. In order to successfully use current techniques for flow routing, they flood local minima and then find a way of routing the flow across the flat surfaces. In this paper, we examine an alternative method for computing flow routing on these flooded surfaces that takes into account the original elev...
