Cross section of heated tube containing forming surface deposits
Grahic Jump Location
Dissolved O2 and fuel temperature measured at locations A and B
Grahic Jump Location
Measured and predicted fuel temperatures at tube exit; 300°C block temperature
Grahic Jump Location
Measured and predicted dissolved O2 fractions for different tube wall temperatures. The curve is the current model prediction, and the symbols represent measurements obtained from NIFTR experiments 13 at a flow rate of 0.125 mL/min.
Grahic Jump Location
Measured and predicted dissolved O2 fractions for current experiments. The curve is the prediction of the current model, and the symbols represent measurements obtained from the current experiments at a flow rate of 16 mL/min using fuel F2827.
Grahic Jump Location
Predicted and measured 13 dissolved O2 removal for NIFTR experiments at a flow rate of 0.125 mL/min and fuel F2827. The curves are predicted values, and the symbols represent measurements.
Grahic Jump Location
Measured and predicted deposition rates along heated tube for fuel F2827 and copper block temperatures of 335°C (8 mL/min), 300°C (16 mL/min), and 270°C (16 mL/min). Predicted deposition rates are represented by the solid curves. In addition, the predicted fraction of dissolved O2 remaining for conditions of a 335°C block temperature and flow rate of 8 mL/min is indicated by a dashed curve.
