Within the framework of the effective field theory (EFT) with correlations, the phase diagrams of a cylindrical spin-1 transverse Ising nanowire are investigated depending on the ratio of the Hamiltonian parameters. We discuss in detail the influence of interfacial coupling, shell surface coupling, and single-ion anisotropy, i.e., crystal field and transverse field ratio on the phase diagrams. We found some characteristic phenomena such as reentrant behavior, tricritical point, and first-order transitions.
