A method to extract macroscopic interface data from microscale rough/porous wall flow fields
Vedanth N Kuchibhotla, Sujit Kumar Sahoo, Y. Sudhakar
Performing geometry-resolved simulations of flows over rough and porous walls is highly expensive due to their multiscale characteristics. Effective models that circumvent this dif…

Higher order homogenized boundary conditions for flows over rough and porous surfaces
Y. Sudhakar, Ugis Lacis, Simon Pasche +1
We derive a homogenized macroscopic model for fluid flows over ordered homogeneous porous surfaces. The unconfined free-flow is described by the Navier-Stokes equation, and the Dar…

Transfer of mass and momentum at rough and porous surfaces
Uǧis Lācis, Y. Sudhakar, Simon Pasche +1
The surface texture of materials plays a critical role in wettability, turbulence and transport phenomena. In order to design surfaces for these applications, it is desirable to ch…
