A modulated gradient model for scalar transport in large-eddy simulation of the atmospheric boundary layer

Fernando Porté Agel, Hao Lu

As a simple alternative to the standard eddy-diffusivity closure, a nonlinear subgrid-scale (SGS) flux model is introduced and implemented in simulations of a neutral atmospheric boundary layer and a stable atmospheric boundary layer. The new model compute ...

Dependence of the most probable and average bond rupture force on the force loading rate: First order correction to the Bell-Evans model

Giovanni Dietler, Serguei Sekatski, Fabrizio Benedetti

The Bell-Evans model which predicts the linear dependence of the most probable intermolecular bond rupture force on the logarithm of stretching force loading rate is usually used to discuss the dynamic force spectroscopy experiment data. This model is cons ...

Considerations on double exponential-based cubatures for the computation of weakly singular Galerkin inner products

Juan Ramon Mosig, Michael Mattes, Athanasios Polymeridis, Ioannis Koufogiannis

Highly accurate and efficient cubatures based on the double exponential quadrature rules are presented for the computation of weakly singular integrals arising in Galerkin mixed potential integral equation formulations. Due to their unique ability to handl ...

A Recursive Acceleration Technique for Static Potential Green's Functions of a Rectangular Cavity Combining Image and Modal Series

Juan Ramon Mosig, Michael Mattes, Sergio Lopez Pena

A hybrid acceleration algorithm for the computation of the static potential Green’s functions of a rectangular cavity is proposed. Similarly to Ewald’s method, it combines the series expansions in terms of images and modes. The main particularity with resp ...

Perturbation Theory Of The Cosmological Log-Density Field

Julien Lesgourgues

The matter density field exhibits a nearly lognormal probability density distribution after entering into the nonlinear regime. Recently, it has been shown that the shape of the power spectrum of a logarithmically transformed density field is very close to ...
