Abstract

The objective of the present study is to understand how the pitch and yaw angle affect the mean flow and turbulence in the wake of the DARPA SUBOFF, an idealized submarine model. Measurements in the wake were performed at ReL = 2.4 × 10⁶. Mean velocity and one-component turbulence measurements were performed using Pitot probes and single normal hot wires in the span-wise plane, 10 diameters downstream of the trailing edge. The range of measured angles of attack and yaw angles were limited to between 0^o and 12^o in part to avoid wind tunnel interference effects. Flow visualization in water at Re_oL = 40×10³ was also performed to inform the wake patterns observed at higher Reynolds number.
