Analytical solution of axi-symmetrical lattice Boltzmann model for cylindrical Couette flows [PDF]
, 2012 Analytical solution for the axi-symmetrical lattice Boltzmann model is obtained for the low-Mach number cylindrical Couette flows. In the hydrodynamic limit, the present solution is in excellent agreement with the result of the Navier-Stokes equation ...

An elementary method for obtaining general solutions to systems of ordinary differential equations
Electronic Journal of Differential Equations, 2021 An analytical method is proposed for finding the general solution of a system of ordinary differential equations (ODEs). The general solution is expressed as a series which in some cases can be summed to give an expression in closed form.
