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…
