Holdup Analysis for Gas-non-Newtonian Liquid Flowthrough Horizontal Helical Coils — Empirical Correlationversus ANN Prediction

摘要

Two-phase gas-liquid flow through curved pipes is much more complex in nature than straight pipes due to the existence of secondary flow and phase separation. Experimental investigations have been carried out to evaluate the holdup for gas-non-Newtonian liquid flow through the helical coils in horizontal orientation. In ANN prediction Multilayer Perceptron (MLP) with backpropagation algorithm and four different conventional transfer functions in the hidden layer is used. The ANN prediction agrees well with the experimental data.
