Abstract The phase shift between pressure and mass flow predicted by an analytic solution for incompressible oscillatory flow in an infinite tube is presented and compared with numerical solutions to the incompressible Navier-Stokes equations for an inertance tube computed by a commercial computational fluid dynamics (CFD) code. Compressible flow equations are also solved by the CFD program and the resulting phase shifts and temperature profiles are reported. A parametric study of the dependence of inertance tube phase shift upon diameter, frequency and length is presented. A turbulence model is included in some runs to evaluate the effect of turbulence on computed phase shift.
