Universal scaling law of an origami paper spring
Bohua Sun
This letter solves an open question of origami paper spring risen by Yoneda et al.(Phys. Rev. E 2019). By using both dimensional analysis and data fitting, a universal scaling law…
A new additive decomposition of velocity gradient
Bohua Sun
To avoid the infinitesimal rotation nature of the Cauchy-Stokes decomposition of velocity gradient, the letter proposes an new additive decomposition in which one part is a SO(3) r…
Classical and Quantum Kepler's Third Law of N-Body System
Bohua Sun
Inspired by amazing result obtained by Semay \cite{semay-1}, this study revisits generalised Kepler's third law of an n-body system from the perspective of dimension analysis. To b…
On Plastic Dislocation Density Tensor
Bohua Sun
This article attempts to clarify an issue regarding the proper definition of plastic dislocation density tensor. This study shows that the Ortiz's and Berdichevsky's plastic disloc…
Singularity-free approximate analytical solution of capillary rise dynamics
Bohua Sun
Capillary rise is one of the most well-known capillarity; however, no single and complete analytic solution has ever been obtained yet. This paper used the singularity-free equatio…
Note on Divergence of the Chapman-Enskog Expansion for Solving Boltzmann Equation
Nanxian Chen, Bohua Sun
Within about a year (1916-1917) Chapman and Enskog independently proposed an important expansion for solving the Boltzmann equation. However, the expansion is divergent or indeterm…
Kepler's third law of n-body periodic orbits in a Newtonian gravitation field
Bohua Sun
This study considers the periodic orbital period of an n-body system from the perspective of dimension analysis. According to characteristics of the n-body system with point masses…
A singularity-free analytic solution of rise dynamics of a liquid in a vertical cylindrical capillary
Xiaoxu Zhong, Bohua Sun, Shijun Liao
Capillary driven flow is a famous problem in fluid dynamics which dates back to Leonardo da Vinci. In this paper, we apply an analytic approximation method for highly nonlinear pro…
The Spatial Scaling Laws of Compressible Turbulence
Bohua Sun
The spatial scaling laws of velocity kinetic energy spectrum for compressible turbulence flow and its density-weighted counterpart have been formulated in terms of wavenumber, diss…
