Abstract: This paper proposes and implements the adaptation of a Malley probe to measure convection velocity in turbulent shear flow and begins to assess its efficacy as a ve-locimeter. Pitot tube mean velocity measurements and Malley probe convection ve-locity measurements were made in a low-Reynolds number incompressible turbulent channel flow, using temperature as a passive scalar, to evaluate, based on Taylor’s frozen turbulence hypothesis, the relationship between convection velocity and mean velocity. Initial results do not support the view that convection velocity is indepen-dent of the local mean velocity, inviting further investigation into the viability of the Malley probe as a non-invasive velocimeter, whether in fluid mechanics research or aviation.
