Renormalization Group and the Ricci flow [PDF]
arXiv, 2010 We discuss from a geometric point of view the connection between the renormalization group flow for non--linear sigma models and the Ricci flow. This offers new perspectives in providing a geometrical landscape for 2D quantum field theories. In particular we argue that the structure of Ricci flow singularities suggests a natural way for extending ...

THE MATHEMATICAL MODEL OF COMPRESSIBLE FLUID FLOW
Mathematical Modelling and Analysis, 2002 In this note we consider the mathematical model of the isothermal compressible fluid flow in an exterior domain O ⊂ R3. In order to solve this problem we apply a decomposition scheme and reduce the nonlinear problem to an operator equation with a contraction operator.

Rotating Cylinder Turbulator Effect on the Heat Transfer of a Nanofluid Flow in a Wavy Divergent Channel [PDF]
Journal of Applied and Computational Mechanics, 2021 In this research study, the numerical Galerkin Finite Element Method (GFEM) is used for forced laminar convection heat transfer of Cu-water nanofluid in a divergent wavy channel including a rotating cylinder turbulator.

Mathematical and Numerical Modeling of Turbulent Flows [PDF]
Anais da Academia Brasileira de Ciências, 2015 The present work is devoted to the development and implementation of a computational framework to perform numerical simulations of low Mach number turbulent flows over complex geometries. The algorithm under consideration is based on a classical predictor-corrector time integration scheme that employs a projection method for the momentum equations. The
