Hodges, Ben R., Auteur ; Teng, Michelle H., Éditeur scientifique |Application of Crank-Nicolson (CN) discretization to the hydrostatic (or shallow-water) free-surface equation in two-dimensional or three-dimensional Reynolds-averaged Navier.Stokes models neglects a second order term. The neglected term is zero[...]

Chan, Andy T., Auteur ; Teng, Michelle H., Éditeur scientifique ; Siddheshwar, Pradeep G. ; Lai, Natalia T. N., Auteur |An analytical methodology is developed to study the pollutant dispersion in a turbulent wind flow over a two dimensional hill with a small slope. As in a typical boundary layer problem, the flow domain is divided into an inner and an outer regio[...]

Fix, James F., Auteur ; Teng, Michelle H., Éditeur scientifique ; Kjos, Lisa, Auteur ; Papanicolaou, Athanasios N., Auteur |Past research environmental hydraulics has established the consideration that small-and large-scale turbulent eddy structures correspond to fast and slow fluctuations within a velocity time series measured at a fixed location. This Work embraces[...]

Dmitry Eskin, Auteur ; Leonenko, Y., Auteur ; Vinogradov, O. ; Teng, Michelle H., Éditeur scientifique |We introduce a simple model of gas-particle flow in a pipeline, which can be used as a tool in engineering design. A chaotic particle motion due to the particle-particle and particle-wall collisions is modeled by analogy with the motion of gas m[...]

Zhou, Hongqiang, Auteur ; Teng, Michelle H., Auteur |In this paper, a preexisting higher-order depth-integrated wave propagation model is extended to include a moving seabed. As a result, the extended model can be applied to both wave propagation and the dynamic process of wave generation by a sea[...]

Lee, Joseph H., Auteur ; Lo, S. H., Auteur ; Lee, K. L. ; Teng, Michelle H., Éditeur scientifique |Duckbill-shaped elastomer valves are often installed on waste-water effluent diffusers, stormwater outfalls, and industrial flow systems to prevent backflow and sediment/salt water intrusion. Unlike fixed diameter nozzles, the flow from a duckbi[...]

Liu, Q. Q., Auteur ; Singh, Vijay P., Auteur ; Teng, Michelle H., Éditeur scientifique |Using a laser-Doppler split-phase measuring technique, the rates of fluctuation in horizontal and vertical directions of pipe flow containing solid particles were observed. Employing these observations the effect of particles on flow turbulence[...]

Brett F. Sanders, Auteur ; Bradford, Scott F., Auteur ; Teng, Michelle H., Éditeur scientifique |High resolution finite volume schemes used to predict mass transport and free surface flows utilize limiters such as Minmod, Double Minmod, and Superbee to prevent spurious oscillations commonly associated with second order accurate schemes. The[...]

Bradford, Scott F., Auteur ; Brett F. Sanders, Auteur ; Teng, Michelle H., Éditeur scientifique |Several techniques are investigated for extending Roe's finite volume method to second-order spatial and temporal accuracy in order to better simulate shallow water flow over nonlevel beds. Specifically, methods reported in the literature for li[...]

Shi, Aimin, Auteur ; Teng, Michelle H., Auteur ; Sou, In Mei, Auteur |This Paper investigate the fundamental behavior of long water waves propagating through branching channels of uniform depth and width. Numerical simulations based on the boussinesq long wave model were carried out to investigate the effect of ch[...]

Subhasish Dey, Auteur ; Zanke, Ulrich C. E., Auteur ; Teng, Michelle H., Éditeur scientifique |An analytical model is presented to determine the threshold bed shear stress for noncohesive sediment motion subject to upward seepage on horizontal sedimentary bed under a stream flow. Hydrodynamic, seepage, and micromechanical forces acting on[...]

Pengzhi Lin, Auteur ; Karunarathna, S. A. S. A., Auteur ; Teng, Michelle H., Éditeur scientifique |A new analytical expression for velocity profile in a fully developed turbulent boundary layer above a porous surface subject to flow injection is derived by solving the coupled Reynolds equations and turbulent kinetic energy equation. The advec[...]

Jung, Kwang Hyo, Auteur ; Teng, Michelle H., Éditeur scientifique ; Jo, Hyo Jae ; Chang, Kuang-An, Auteur |The Viscous effect on the roll motion of a rectangular structure was investigated in a two-dimensional wave tank. The Structure was used to simulate a simplified barge in the beam sea condition. The Structure with a draft one half of its height [...]
