Is a UCM fluid flow near a stationary point always singular? [PDF]
arXiv, 2016 Frequently observed divergence of numerical solutions to benchmark flows of the UCM viscoelastic fluid is a known and widely discussed issue. Some authors consider such singularities "invincible". The article argues this position, to which end it considers two typical flows with a stagnation point, often a place of the flows' singularity: counterflows ...

Is a UCM fluid flow near a stationary point always singular? - Part II [PDF]
arXiv, 2016 Oftentimes observed divergence of numerical solutions to benchmark flows of the UCM viscoelastic fluid is a known and widely discussed issue. Some authors consider such singularities 'invincible'. Following the previous research, the article gives more arguments against this position, for which it considers two typical flows with a stagnation point ...

On the particle paths and the stagnation points in small-amplitude deep-water waves [PDF]
, 2012 In order to obtain quite precise information about the shape of the particle paths below small-amplitude gravity waves travelling on irrotational deep water, analytic solutions of the nonlinear differential equation system describing the particle motion are provided. All these solutions are not closed curves. Some particle trajectories are peakon-like,

Topological structures in the Husimi flow [PDF]
, 2015 We study the topological properties of the quantum phase space current in the Husimi representation, focusing on the dynamical differences, induced by these properties, between the quantum and the classical flows. We show that the zeros of the Husimi function are stagnation points of the current and have a nonzero topological charge.

Effects of Surface Roughness on Stagnation Heat Transfer of Impinging Liquid Jet on Metal Surface
Journal of Fluid Science and Technology, 2010 The liquid jet impingement with phase change heat transfer has long been an attractive method of cooling especially in steelmaking process and heat treatment in metals.

MHD stagnation point flow toward a linearly-stretching thermally-insulated sheet with induced magnetic field [PDF]
arXiv, 2016 The equations governing the magnetohydrodynamic stagnation point flow toward a non-conducting, thermally insulated, nonporous, linearly stretching sheet are cast in a self similar form. Consistent boundary conditions on the velocity, magnetic field and temperature are invoked. The flow problem involves three parameters- the magnetic Prandtl number, the

Numerical Investigation of Nonisothermal Reversed Stagnation-point Flow [PDF]
arXiv, 2013 This thesis investigates the nature of the development of two-dimensional laminar nonisothermal flow of an incompressible fluid close to the reversed stagnation-point. Proudman and Johnson (1962) \cite{proudman1962boundary} first studied the flow and obtained an asymptotic solution by neglecting the viscous terms. This is not practice in neglecting the

Stretched Flow of Casson Fluid with Variable Thermal Conductivity
Walailak Journal of Science and Technology, 2012 This paper looks at the stagnation point flow of Casson fluid towards a stretching surface. In addition, heat transfer analysis is discussed. The thermal conductivity varies linearly with temperature. Series solutions are first presented and then studied

Group classification of steady two-dimensional boundary-layer stagnation-point flow equations [PDF]
arXiv, 2010 Lie symmetry group method is applied to study the boundary-layer equations for two-dimensional steady flow of an incompressible, viscous fluid near a stagnation point at a heated stretching sheet placed in a porous medium equation. The symmetry group and its optimal system are given, and group invariant solutions associated to the symmetries are ...

Singularities of axisymmetric free surface flows with gravity [PDF]
arXiv, 2012 We consider a steady axisymmetric solution of the Euler equations for a fluid (incompressible and with zero vorticity) with a free surface, acted on only by gravity. We analyze stagnation points as well as points on the axis of symmetry. At points on the axis of symmetry which are not stagnation points, constant velocity motion is the only blow-up ...
