vibrational characteristics of a spinning thermally affected cylindrical shell conveying viscous fluid flow carrying spring-mass systems

In this article, the vibrational behavior of a spinning cylindrical thick shell carrying springmasssystems and conveying viscos fluid flow under various temperature distributions isinvestigated. this structure rotates about axial direction and the formulations include thecoriolis and centrifugal effects. in addition, this system is conveying viscous fluid, and the relatedforce is calculated by modified navier –stokes relation considering slip boundary condition andknudsen number. the modeled cylindrical thick shell, its equations of motion, and boundaryconditions are derived by the principle of minimum total potential energy and based on a newthree-dimensional refined higher-order theory (rhost). for the first time in the present study,attached mass-spring systems has been considered in the rotating cylindrical thick shellsconveying viscous fluid flow. the accuracy of the presented model is verified with previousstudies. the novelty of the current study is consideration of the rotation, various temperaturedistributions, mass-spring systems and conveying viscous fluid flow implemented on proposedmodel using rhost. generalized differential quadrature method (gdqm) is presented todiscretize the model and to approximate the governing equations. in this study the simplysupported conditions has been applied to edges θ=0,2π and cantilever boundary conditionshas been studied in x=0, l. finally, the effects of the velocity of viscous fluid flow, angularvelocity, temperature changes and spring-mass systems on the critical speed, critical velocity,critical temperature and natural frequency of the structure are investigated.
