Abstract

The start-up of natural convection boundary layer flow on a semi-infinite heated plate is simulated using a time-accurate finite-volume Navier-Stokes solver. The flow exhibits an initially unsteady one-dimensional flow which transits to a steady two-dimensional flow with the passage of a signal travelling up the plate. The travelling signal is shown to consist of an initial rapidly travelling component localised in the region of the plate origin, followed by a slower travelling component. The velocity of the slower travelling component is shown to be well predicted by the maximum velocity travelling wave obtained from a stability analysis.
