An optimized dispersion-relation-preserving combined compact difference scheme to solve advection equations
Ching-Hao Yu, Dan Wang, Zhiguo He +1
In this study, we first present an improved version of the classical sixth-order combined compact difference (CCD6) scheme to enhance the convective stability of advection equation…
Is it appropriate to model turbidity currents with the three-equation model?
Peng Hu, Thomas Pähtz, Zhiguo He
The three-equation model (TEM) was developed in the 1980s to model turbidity currents (TCs) and has been widely used ever since. However, its physical justification was questioned…
The fluctuation energy balance in non-suspended fluid-mediated particle transport
Thomas Pähtz, Orencio Durán, Tuan-Duc Ho +2
Here we compare two extreme regimes of non-suspended fluid-mediated particle transport, transport in light and heavy fluids ("saltation" and "bedload", respectively), regarding the…
Electric Field and Humidity Trigger Contact Electrification
Yanzhen Zhang, Thomas Pähtz, Yonghong Liu +5
Here, we study the old problem of why identical insulators can charge one another on contact. We perform several experiments showing that, if driven by a preexisting electric field…
