We investigate the characteristics of the transition from laminar to turbulent flow in the microtube with a diameter of 310 μm. The microscopic particle image velocimetry is used to measure the water flow at Re=1600–2500 in the microtube. It is fo

The limit cycles in the Lorenz system near the stationary points are analysed numerically. A plane in phase space of the linear Lorenz system is used to locate suitable initial points of trajectories near the limit cycles. The numerical results show

This article proposes an extension that includes an analytical solution for the coagulation coefficient of bipolarly charged particles by an external electric field with the effect of Coulomb force, based on the known analytical solution for the coag

A simple criterion is presented to determine whether or not charged particles will adhere to the collecting plate in a wire-plate electrostatic precipitator (ESP). Based on the energy balance, it was determined that when a charged particle collides w

A stationary vortex phenomenon above a nondelta low-aspect-ratio wing was obtained in three-dimensional unsteady numerical simulation. Flow visualization is conducted in water channel using hydrogen bubbles. The results verify that there is a vortex
