“…Some advantages of ITWNDT as intuitive test results, single-sided testing, non-contact, large area detection and quantitative detection were successfully applied in the aerospace, power generation, automotive, construction and other fields [5]- [10]. S. Marinetti [11]- [12], E. Grizato [13]- [14], D. Ambrosini [15], M. Jonsson [16] and Yang Jing [17] studied the application of ITWNDT in corrosion detection, and achieved relatively good results. Notwithstanding this, the influence factors in the thermal Wave NDT are still not completely exploited.…”

Due to the disadvantages of traditional NDT methods for liquid propellant tank corrosion detection, Thermal Wave Nondestructive Testing (ITWNDT) technology was applied. The heat exchange process of thermal wave in corrosion tank was simulated by the numerical method. Parameters of TWNDT as the best detection time (t best ), the maximum surface temperature difference (ΔT max ), and the temperature difference holding time (τ ΔT>0.1 ) were discussed as the targets. Based on these parameters, factors influencing the detection results of tank materials, dressed liquid (also considered as the corrosion product), pit characters (depth and size), heat flux and thermal excitation time length (pulsed width), environmental conditions and other factors were analyzed. Simulation results show that ITWNDT can identify the defect depth, size and position rapidly and effectively. Material properties of the tank were influencing the t best , ΔT max and τ ΔT>0.1 , while the dressed liquid, thermal excitation parameters and the conditions of environment do not influence the t best . Pit characters of the depth and size have close relationship with t best and ΔT max , therefore, for a tank with certain material and certain liquid dressed in, the pit corrosion damage can be accurately evaluated.
