Smooth-Wall Boundary Conditions For Dissipation-Based Turbulence Models, W. F. Phillips, Doug F. Hunsaker, Robert E. Spall
Smooth-Wall Boundary Conditions For Dissipation-Based Turbulence Models, W. F. Phillips, Doug F. Hunsaker, Robert E. Spall
Mechanical and Aerospace Engineering Faculty Publications
It is shown that the smooth-wall boundary conditions specified for commonly used dissipation-based turbulence models are mathematically incorrect. It is demonstrated that when these traditional wall boundary conditions are used, the resulting formulations allow an infinite number of solutions. Furthermore, these solutions do not enforce energy conservation and they do not properly enforce the no-slip condition at a smooth surface. This is true for all dissipation-based turbulence models, including the k-ε, k-ω, and k-ζ models. Physically correct wall boundary conditions must force both k and its gradient to zero at a smooth wall. Enforcing these two boundary conditions on k …

Solar Radiative Heating Of Fiber-Optic Cables Used To Monitor Temperatures In Water, Bethany T. Neilson, Christine E. Hatch, Heng Ban, Scott W. Tyler
Solar Radiative Heating Of Fiber-Optic Cables Used To Monitor Temperatures In Water, Bethany T. Neilson, Christine E. Hatch, Heng Ban, Scott W. Tyler
Mechanical and Aerospace Engineering Faculty Publications
In recent years, applications of distributed temperature sensing (DTS) have increased in number and diversity. Because fiber-optic cables used for DTS are typically sheathed in dark UV-resistant materials, the question arises as to how shortwave solar radiation penetrating a water column influences the accuracy of absolute DTS-derived temperatures in aquatic applications. To quantify these effects, we completed a modeling effort that accounts for the effects of radiation and convection on a submersed cable to predict when solar heating may be important. Results indicate that for cables installed at shallow depths in clear, low-velocity water bodies, measurable heating of the cable …

Effect Of Electrical Double Layer On Electric Conductivity And Pressure Drop In A Pressure-Driven Microchannel Flow, Heng Ban, Bochuan Lin, Zhourui Song
Effect Of Electrical Double Layer On Electric Conductivity And Pressure Drop In A Pressure-Driven Microchannel Flow, Heng Ban, Bochuan Lin, Zhourui Song
Mechanical and Aerospace Engineering Faculty Publications
The effect of an electrical double layer (EDL) on microchannel flow has been studied widely, and a constant bulk electric conductivity is often used in calculations of flow rate or pressure drop. In our experimental study of pressure-driven micropipette flows, the pipette diameter is on the same order of magnitude as the Debye length. The overlapping EDL resulted in a much higher electric conductivity, lower streaming potential, and lower electroviscous effect. To elucidate the effect of overlapping EDL, this paper developed a simple model for water flow without salts or dissolved gases (such as CO2) inside a two-dimensional …
