Development of pressure difference technique using three dimensional effect in a horizontal pipe

An experimental investigation of wave-like gas-solid flow in a horizontal pipe was conducted. A simple method was developed to monitor the waves and their properties. A non-intrusive measuring technique was also developed to monitor the transition from a dilute phase flow to wave-like flow. Pressure difference measurement provided detailed information about the flow within the pipeline. Finally, the experimental results obtained by the pressure difference technique were compared to those of the capacitance measuring technique.
