In the part 2, in order to verify and demonstrate the application of NHAT, two simulations are performed. First, the aerodynamic vibration of a square prism on a single-degree-of freedom elastic model is simulated in three-dimensional flow. Then, the air pressure field acting on the model is analyzed by means of the Proper Orthogonal Decomposition. Second, the aerodynamic vibration of a square prism is simulated using a multi-degree-of freedom elasto-plastic model. These simulations prove the broad applicability of NHAT. In additional, it is discussed whether NHAT can simulate the vibration of structures in liquid sodium even under in air flow or not.
