Soheil Gholamreza-Kashi, Auteur ; Robert J. Martinuzzi, Auteur ; Raouf E. Baddour, Auteur |The turbulence structure of a rectangular surface jet is compared to that of the three-dimensional free and wall jets. The surface jet turbulence quantities are mapped using laser Doppler velocimetry. In general, the turbulence structure of thes[...]

Joung, Youghoon, Auteur ; Choi, Sung-Uk, Auteur ; Choi, Jung-II ; Robert J. Martinuzzi, Éditeur scientifique |A direct numerical simulation of turbulent flow in a square duct was performed for a Reynolds number based on bulk streamwise velocity and duct height equal to 4,440. The mechanism by which secondary flows are generated in a square duct was inve[...]

Yang, W. C., Auteur ; Robert J. Martinuzzi, Éditeur scientifique ; Hsieh, C. M. ; Hwang, Robert R., Auteur |The purpose of the present study is to develop a numerical model for the investigation of water waves propagating over a pair of impermeable submerged obstacles. The mathematic model is formulated by coupling solutions of the Navier—Stokes equat[...]

Srinivas, Y., Auteur ; Biswas, G., Auteur ; Parihar, A. S. ; Ranjan, R. ; Robert J. Martinuzzi, Éditeur scientifique |Flow past a square cylinder at a reynolds number of 21,400 has been studied numerically using the large-eddy simulation technique. A dynamic subgrid-scale stress model has been used for the small scales of turbulence. The Time-and span-averaged [...]

Mori, Nobuhito, Auteur ; Suzuki, Takuma, Auteur ; Kakuno, Shohachi ; Robert J. Martinuzzi |Acoustic doppler velocimeter (ADV) are useful and powerful for measurements of mean and turbulent components of fluids in both hydraulic experimental facilities and fields. However, it is difficult to use the ADV in bubbly flows because air bubb[...]

Coleman, S. E., Auteur ; Robert J. Martinuzzi, Éditeur scientifique ; Schlicke, E. ; McLean, S. R. ; Nikora, V. I., Auteur |A series of experiments was undertaken to assess fully rough turbulent subcritical flow over two-dimensional transverse repeated-rib roughness of varying spacing λ/h=1.16 (roughness spacing/height ratio), with h/H=0.09 (roughness height/flow de[...]
