The Canadian Journal of Chemical Engineering, EarlyView.Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Compressible Lagrangian hydrodynamics without Lagrangian cells [PDF]
, 2005 The partial differential Eqs [2.1, 2.2, and 2.3], along with the equation of state 2.4, which describe the time evolution of compressible fluid flow can be solved without the use of a Lagrangian mesh. The method follows embedded fluid points and uses finite difference approximations to \(\vec \nabla\)P and \(\vec \nabla\) · \(\vec u\) to update p ...

Special Lagrangian cones [PDF]
American Journal of Mathematics, 2004 We study special Lagrangian cones in [inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="01i" /] with isolated singularities especially the case n = 3. Our main result constructs an infinite family of special Lagrangian cones in [inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="02i" /] each of which has a ...

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

Symmetry, Integrability and Geometry: Methods and Applications, 2011 This paper deals with the Lagrangian analogue of symplectic or point reduction by stages. We develop Routh reduction as a reduction technique that preserves the Lagrangian nature of the dynamics.

ELECTROWEAK EFFECTIVE LAGRANGIANS [PDF]
International Journal of Modern Physics A, 1994 In this paper I review several aspects of the use of effective Lagrangians in (mainly) electroweak physics. The conditions under which this approach is reliable and useful, as well as the limitations of the formalism, are detailed. Various applications are also presented.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study investigates how internal governance design supports credible ESG performance by distinguishing between Incentive and Oversight Architectures. Using 13,993 firm‐year observations of US nonfinancial firms from 2018 to 2024, we estimate fixed effects and two‐step system GMM models.
