Wake Evolution of Wing-Body Configuration from Roll-Up to Vortex Decay [PDF]

, 2012
The development of aircraft’s wake vortex from the roll-up until vortex decay is studied. An aircraft model and the surrounding flow field obtained from high-fidelity Reynolds-averaged Navier-Stokes simulation are swept through a ground-fixed ...

Mass corrections to the tau decay rate

Zeitschrift f�r Physik C Particles and Fields, 1993
In this note radiative corrections to the total hadronic decay rate of the $τ$-lepton are studied employing perturbative QCD and the operator product expansion. We calculate quadratic quark mass corrections to the decay rate ration $R_τ$ to the order ${\cal O}(α_s^2 m^2)$ and find that they contribute appreciably to the Cabbibo supressed decay modes of

Measurement and analysis of electric potential decay in corona charged low-density polyethylene films [PDF]

, 2007
In this paper, corona charged LDPE film was tested using a standard static potential monitor and the pulsed electro-acoustic (PEA) technique to observe the surface potential decay.

Stability and exponential decay for two-dimensional Boussinesq equations with partial viscosity and thermal diffusion

Advances in Nonlinear Analysis
In this work, we study the two-dimensional anisotropic Boussinesq equations, incorporating only horizontal dissipation in the tangential velocity and horizontal thermal diffusion. When the spatial domain is T×R $\mathbb{T}{\times}\mathbb{R}$ , this paper
