A numerical study is made of the transient flow of a gas contained in an infinite cir-cular cylinder which impulsively starts rotating about the central longitudinal axiswith angular frequency f2. As a sequel to the previous work which reported on theearly-time behavior of the flow, descriptions are given of the flows at moderate andlarge times leading to the steady state. Attention is confined to the situations in whichthe reference system Ekman number E is small, and the cornpressibility effect issubstantial. Two types of the sidewall thermal boundary condition are considered: anisothermal wall and an adiabatic wall. Systematically-organized numerical solutionsare obtained by solving the full, time-dependent, cornpressible Navier-Stokes equa-lions. The details of the evolutions of the velocity, density and temperature fields arepresented. The evolutionary profiles of the temperature fields show profounddifferences between the two sidewall thermal conditions.
