Effective field theory for hydrodynamics: thermodynamics, and the derivative expansion
Effective field theory hydrodynamics thermodynamics derivative expansion
2011/8/19
Abstract: We consider the low-energy effective field theory describing the infrared dynamics of non-dissipative fluids. We extend previous work to accommodate conserved charges, and we clarify the mat...
A spherical cavity expansion model for penetration of ogival-nosed projectiles into concrete targets with shear-dilatancy
Spherical cavity expansion Shear dilatancy Ogival-nosed projectile Concrete target Penetration Perforation
2012/2/28
A dynamic spherical cavity-expansion penetration model is suggested herein to predict the penetration and perforation of concrete targets struck normally by ogivalnosed projectiles. Shear dilatancy as...
Derivation of a second-order model for Reynolds stress using renormalization group analysis and the two-scale expansion technique
Turbulent modeling Renormalization group Two-scale expansion Reynolds stress transport equation Second-order model

With the two-scale expansion technique proposed by Yoshizawa, the turbulent fluctuating field is expanded around the isotropic field. At a low-order two-scale expansion, applying the mode coupling app...
