Abstract Atmospheric new particle formation (NPF) is a naturally occurring phenomenon, during which high concentrations of sub-10 nm particles are created through gas to particle conversion. The NPF is observed in multiple environments around the wor

Publikováno v: AppliedMath, Vol 4, Iss 2, Pp 743-762 (2024)

The relationship between the inverse Langevin function and the proposed r0-r1-Lambert W function is defined. The derived relationship leads to new approximations for the inverse Langevin function with lower relative error bounds than comparable publi

Effect of Sediment Form and Form Distribution on Porosity: A Simulation Study Based on the Discrete Element Method

Autor: Rettinger, Christoph, Rüde, Ulrich, Vollmer, Stefan, Frings, Roy M.

Porosity is one of the key properties of dense particle packings like sediment deposits and is influenced by a multitude of grain characteristics such as their size distribution and shape. In the present work, we focus on the form, a specific aspect
