Laser-Doppler velocity measurements in water are reported for the flow in the plane of symmetry of a turbulent spot. The unsteady mean flow, defined as an ensemble average, is fitted to a conical growth law by using data at three streamwise stations to determine the virtual origin in x and t. The two-dimensional unsteady stream function is expressed as 1fr = U~ tg(£, r/) in conical similarity co-ordinates g = xfUoot and 1J = y jU00 t. In these co-ordinates, the equations for the unsteady… CONTINUE READING
