Numerical modeling of three-phase flow through a Venturi meter using the LSSVM algorithm
One of the challenging problems in the Oil & Gas industry is accurate and reliable multiphase flow rate measurement in a three-phase flow. Application of methods with minimized uncertainty is required in the industry. Previous developed correlations for two-phase flow are complex and not capable of three-phase flow. Hence phase behavior identification in different conditions to designing and mo...
متن کاملK V Santhosh: Fusion of Venturi and Ultrasonic Flow Meter for Enhanced Flow Meter Characteristics Using Fuzzy Logic
This paper proposes a technique for measurement of liquid flow using venturi and ultrasonic flow meter(UFM) to have following objectives a) to design a multi-sensor data fusion (MSDF) architecture for using both the sensors, b) improve sensitivity and linearity of venturi and ultrasonic flow meter and c) detect and diagnosis of faults in sensor if any. Fuzzy logic algorithm is used to fuse outp...
متن کاملApplication of Information Complexity in Principal Component Regression Modeling of the Venturi Meter Drift
In principal component regression there is a problem of selecting the number of principal components to be retained in the model. Those principal components corresponding to near-zero eigenvalues can ruin the precision of the regression coefficients estimator and therefore must be eliminated from the model. However, when the eigenspectrum gradually decays, it is difficult to decide how many pri...
