▎ 摘  要

In this work, dynamics response associated with a curved pipe which is made of reinforced composite material via graphene nanoplatelets-GPLs-subjected to a supersonic airflow as well as thermal loading is examined. The thermal environment conditions are obtained using heat-transfer continuum equations. Quasi-2D hyperbolic refined high-order shear deformation theory is employed to extract the formulations, and then these formulations are solved through Generalized Differential Quadrature Method (GDQM). The results are verified by using results from other papers along with results extracted from COMSOL multi-physics software. The influence of yaw angle, hydrodynamic pressure, geometry properties, Mach number, and temperature change of the current structure on the vibrational behavior of the GPLRC tilted curved pipe subjected to supersonic airflow was studied. One of the amazing results is that the influence of aerodynamic pressure on the airflow stability related to the system has a remarkable dependency on the value of yaw angle. Another amazing outcome for future analysis is that not only increasing the aerodynamic pressure could expand the stability area but also flutter phenomena happen at the higher value of Mach number.
