摘要：Accurate temperature and velocity measurement of fluid is of vital importance for CO2 Capture and Storage (CCS). The aims of this study were to evaluate the application of several magnetic resonance imaging (MRI) temperature measurement techniques in CCS and to simultaneously measure velocity and temperature distribution for flow field. First, the relations between MRI parameters including apparent self-diffusion coefficient (D), longitudinal relaxation time (T (1)), longitudinal equilibrium magnetization (M (0)) and temperature for three different samples were investigated. The results show that in high magnetic strength field the linear relationship between D and temperature is better than M (0)-T and T (1)-T in terms of accuracy and sensitivity. Then we used inversion recovery tagging method to simultaneously measure temperature and velocity of water flowing through a heated vessel. Temperature measured by IR-tagging method is within a deviation of 2 A degrees C from the numerical results obtained by computational fluid dynamics.
