Examples
- Density wave theory
密度波理论 - This theoretic model employs the basic idea of correlation measurement , achieve the density wave speed by the correlation of the signals of upper and lower sensors , and get the total flow rate and water cut through the theoretic relationship of density wave speed and total flow rate as well as holdup with the help of drift flux model so as to accomplish the oil / water two - phase flow measurement at last , using the limited available experiment data , the theoretic model has been simplified into an applicable linear alternative which is suitable to homogeneous oil / water two - phase flow measurement to accomplish the oil / water two - phase flow measurement using the density wave phenomena is of highly theoretically valuable for density wave theory research as well as oilavater two - phase flow measurement research . to develop new type oil / water two - phase flow instrumentation based on this theoretic measurement method will be very applicable and promising
