제목 Inverse Modeling of Rheological Parameter of Dense Suspension Using Artificial Neural Networks
초록 For suspension flow modeling, it is critical to determine rheological parameters using measurements. While a rheometer can be used to determine the rheological parameters, the rheology may change during subsequent flow after the measurement. This study proposes work an inverse model for predicting rheological parameters from pressure drops measured in a dense suspension pipe flow system. The flow data were generated using a power-law fluid and the Weissenberg-Rabinowitsch-Mooney-Schofield (WRMS) method, which establishes a relationship between pressure drop and flow rate for generalized Newtonian fluids. The flow data was used to train a direct neural network model. The pressure drop is calculated directly from the rheological parameters using this direct model. By minimizing the difference between the measured pressure drop and the direct model output, the inverse model determines rheological parameters. As a result of optimization, the rheological parameter, n, was successfully determined.
