Jiahao Tian, Auteur ; Roussinova Vesselina, Auteur ; Ram Balachandar, Auteur |In this study, the characteristics of a round turbulent jet in the vicinity of a free surface are investigated. The jet issued from a nozzle located at a depth five times the nozzle diameter (d = 10 mm) below and parallel to the free surface. Th[...]

Bushra Afzal, Auteur ; Abdullah Al Faruque, Auteur ; Ram Balachandar, Auteur |Three series of experiments were conducted to study the effect of Reynolds number, near-wall perturbation and turbulence on the velocity characteristics of smooth open-channel flows. Measurements were carried out using a laser Doppler anemometer[...]

Alex Bey, Auteur ; M. A. A. Faruque, Auteur ; Ram Balachandar, Auteur |An experimental program was carried out to understand the role of channel width and varying tailwater depth on the scour caused by a plane wall jet. To this end, four groups of tests, denoted as A, B, C and D, were conducted. In group A, during [...]

Tirupati Bolisetti, Auteur ; Stanley Reitsma, Auteur ; Ram Balachandar, Auteur |This paper presents the results of an experimental investigation performed to understand the processes influencing the injection of colloidal silica grout into porous media. Based on the combined analysis of grout injection pressures and the vis[...]

Partha Sarathi, Auteur ; M. A. A. Faruque, Auteur ; Ram Balachandar, Auteur |In this paper, an effort is made to better understand the scour caused by submerged square jets in a cohesionless sand bed. The variables of interest are the densimetric Froude number, the tailwater depth and sediment grain size. Experiments wer[...]

Arindam Singha, Auteur ; A.-M. Shinneeb, Auteur ; Ram Balachandar, Auteur |This paper reports particle-image velocimetry measurements of instantaneous velocity fields in the wake of a sharp-edged bluff body immersed vertically in a shallow smooth open channel flow. The maximum flow velocity was 0.19 m/s and the Reynold[...]

Roussinova Vesselina, Auteur ; Nihar Biswas, Auteur ; Ram Balachandar, Auteur |This study reexamines the mean velocity scaling as well as higher order turbulent moments in a uniform smooth open channel flow with three different aspect ratios. In the overlap region, the velocity profiles follow the classical logarithmic law[...]

Girish Sankar, Auteur ; Ram Balachandar, Auteur ; Rupp Carriveau, Auteur |Characteristics of a square jet near a free surface were experimentally studied at four different tailwater depths. Velocity measurements were made with a two-component laser Doppler anemometer at five stations along the jet streamwise axis. A q[...]

Arindam Singha, Auteur ; Md. Abdullah Al Faruque, Auteur ; Ram Balachandar, Auteur |The effect of seepage (injection and suction) on the dynamics of vortices and large-scale structures in a rough open channel flow was examined experimentally. The velocity measurements in the open channel flow were carried out using particle ima[...]
