Experimental and Modeling Studies of Two-Point Stochastic Structure in Turbulent Pipe Flow

Experimental and modeling studies of large scale eddies of turbulent structure far from the wall region have been conducted in a vertical fully developed water pipe flow (D = 10.16 cm). The turbulent structure was investigated using space and space-time correlations. The axial and radial velocity components were obtained simultaneously at two points in the flow field with two hot film anemometers x-probes. Correlation measurements were performed initially with the fixed probe at Y/R = 0.5 from the pipe wall and with axial and radial separations of the movable probe. More detailed measurements were performed with the fixed probe at Y/R = 0.35 from the pipe wall with combined axial and radial separations of the movable probe to give net separations in planes inclined at 0(DEGREES), 10(DEGREES), 20(DEGREES), 40(DEGREES), 65(DEGREES) and 90(DEGREES) with respect to either the downstream or the upstream direction.
