A non-intrusive method to measure the particle velocities in dilute-phase pneumatic conveying is described. The method is based on correlating signals, which are measured in two flow cross-sections. The cross-correlation function generated provides information about the time it takes for a particle to travel between the measurement planes. Knowing the inter-plane distance and the time delay, th...

Abstract: This paper proposed three-dimensional numerical simulation method by coupling of electrostatic and fluid fields to evaluating the performance of electrical sensor in the concentration measurement of gas/solid two-phase flow. Compared with the static numerical simulation, this real-time dynamic 3-D simulation method can research on a designed capacitance sensor combining the dynamic ch...

Abstract The article presents an investigation of the stabilization a cantilever pipe discharging fluid using electromagnetic actuators transformer type. With flow velocity reaching critical value, straight equilibrium position becomes unstable, and self-excited lateral vibrations arise. Supplying voltage to yields two opposite effects. First, each attracts pipe, thus introduces effect negative...
