Conditions for the existence of an inertial subrange in turbulent flow

P. Bradshaw (1967)

Under review
The determination of local turbulent skin friction from observations in the viscous sub-layer

P. Bradshaw; N. Gregory (1959)

Observations made in the viscous sub-layer of turbulent shear flows with small surface pitot-tubes and hot wires show that such instruments give accurate values of boundaryiayer skin friction, at least in zero pressure ...
The effect of initial conditions on the development of turbulent boundary layers

P. Bradshaw; D. H. Ferriss (1968)
The effect of turbulence on static-pressure tubes

P. Bradshaw; D. G. Goodman (1966)

Summary. Measurements on the centreline of a circular jet confirm the suggestion of Barat and Toomre that the error in static-tube reading due to turbulent fluctuations depends on the ratio of the size of the tube to the ...
Measurements of Free-Stream Turbulence in some Low-Speed Tunnels at N.P.L.

P. Bradshaw; D. H. Ferriss (1962)

The r.m.s, fluctuation levels in the older low-speed tunnels at N.P.L. are found to be as follows: Compressed Air Tunnel, 0.3% rising to 0.6% at maximum speed and pressure; 13 ft x 9 ft Tunnel, 0.05 -> 0.2%; 9 ft x 7 ft ...
The N.P.L. 59 in. x 9 in. boundary-layer tunnel

P. Bradshaw; G. E. Hellens (1964)

Under review
The normal impingement of a circular air jet on a flat surface

P. Bradshaw; Edna M. Love (1959)

Measurements of velocity magnitude and direction, static pressure, and skin friction have been made in a circular turbulent jet impinging normally on a flat surface. The speed in the jet just before impingement was 135 ...
The response of a constant-pressure turbulent boundary layer to the sudden application of an adverse pressure gradient

P. Bradshaw (1967)

Mean velocity, turbulent intensity and shear stress have been measured in a turbulent boundary layer which passes from a region of constant free-stream velocity U1 to a region with U1 axpower-0.255. Further measurements ...
The spectral energy balance in a turbulent mixing layer

P. Bradshaw; D. H. Ferriss (1967)
Turbulent wall jets with and without an external stream

P. Bradshaw; M. T. Gee (1960)

The results are presented of experiments on wall jets in still air on flat and curved surfaces, and beneath an external stream in presence and absence of pressure gradient and initial boundary layer. It is found that the ...
