This is the first research on smart control and frequency analysis of a cylindrical sandwich nanoshell in framework numerical-based generalized differential quadrature method (2D-GDQM). The current nanostructure made honeycomb core piezoelectric face sheets as sensor actuator (PFSA). For modeling size-dependent nanoshell, nonlocal stress-strain gradient theory (NSGT) presented. Also, this under conveying viscous fluid, related force calculated by modified formulation Navier–Stokes. structure rotates around its axial direction. stresses strains are obtained using higher-order shear deformation (HSDT). external voltage applied to layer, Proportional-Derivative (PD) controller used for output control. Governing equations boundary conditions implementing Hamilton's principle. results show that geometry core, PD controller, velocity fluid flow, length radius ratio (L/R), have significant influence characteristics nanoshell. Another important consequence applying leads an increase critical flow nanostructure.

Abstract Heat transfer rate is numerically analyzed in convective flow of Al 2 O 3 ‐Ag/ H hybrid nanoliquid through a stretching sheet by incorporating induced magnetic field. Results entropy generation system are evaluated as well. Considered physical factors associated with heat parameter and viscous dissipation. The nonlinear partial differential equations modeled dimensionally simplified implementing boundary layer approximation assumption proper similarity transformations. Adam's Bashforth method applied to get highly accurate stable numerical solutions. Numerical results variables, number quantities interpreted way graphs bar charts perceive the extensive significance problem. It visualized that rise numeric values mixed convection λ 1 leads enhance velocity; Nusselt while suppress temperature. High magnitude δ augments velocity temperature but reverse behavior observed for number. Moreover, factor dissipation significantly modifies under effect no‐slip condition on sheet. present study useful different fields industries, technological processes, mechanical electrical processes due applications nanofluid improved mass transfer.
