Small model airplane jet engines can have an outer diameter of less than four inches and can spin at more than 100,000 revolutions per minute. Under such conditions, the rotational effects are expected to be considerably stronger than for larger commercial engines. To increase the thrust of a small turbojet engine, an afterburner was designed. The design was based on a Parametric Cycle Analysis and an ANSYS FLUENT simulation to analyze the flow and ignition in the afterburner. Moreover, to investigate how rotation affects the mean flow, numerical simulations were performed of a linear and annular low-pressure turbine cascade for a Reynolds number of Re = 5,000. For these simulations, terms accounting for the Coriolis and centrifugal accelerations were added to the right-hand side of an existing Navier-Stokes code. Simulations were performed without and with rotational effects. The parameters for the latter were chosen to model a small model engine and a larger military engine. A comparison of the results obtained from the simulations revealed several interesting differences: The rotational effects were found to cause a spanwise pressure gradient and a noticeably asymmetric suction surface skin-friction line topology. In particular, the passage vortex on the inboard side was much stronger than for the case without rotation and the passage vortex on the outboard side was missing.
