Cover Story: We developed long short-term memory (LSTM) networks for thermocouple sensor predictions by training on the sensor’s own prior history, and transfer learning LSTM (TL-LSTM) by training on a correlated sensor’s history.  Data were obtained from a flow loop filled with water and with liquid metal Galinstan for a range of flow regimes. The root mean square error (RMSE) for the test segment of time series was shown to linearly increase with the Reynolds number (Re) for both fluids. Using linear correlations, we estimated the range of values of Re for which RMSE is smaller than the measurement uncertainty. For both fluids, LSTM and TL-LSTM provide reliable estimations of temperature for typical flow regimes in a nuclear reactor. View this paper
