ab: Summary: An investigation of the efficiency of multigrid algorithms for the
    compressible Navier-Stokes equations is presented. The computational
    code that forms the basis for this investigation utilises a hybrid
    Godunov-type method and central differences for discretising the
    inviscid and viscous fluxes, respectively, as well as
    implicit-unfactored and explicit solvers. To accelerate the numerical
    convergence towards a steady state solution we have employed a
    non-linear multigrid method. Further, we have also implemented a
    dynamically adaptive multigrid algorithm in conjunction with the
    explicit solver. Computations have been conducted for low Reynolds
    number compressible flows around an aerofoil both at subsonic and
    supersonic flow conditions. Results from several numerical experiments
    are presented in order to examine the performance of the multigrid
    algorithms in conjunction with the explicit and implicit solvers.
