A variational level set methodology without reinitialization for the prediction of equilibrium interfaces over arbitrary solid surfaces
Karim Alamé, Sreevatsa Anantharamu, Krishnan Mahesh
A robust numerical methodology to predict equilibrium interfaces over arbitrary solid surfaces is developed. The kernel of the proposed method is the distance regularized level set…
Direct numerical simulation of turbulent channel flow over random rough surfaces
R. Ma, K. Alamé, K. Mahesh
Direct numerical simulation (DNS) of flow in a turbulent channel with a random rough wall is performed at and . The roughness geometry corresponds to the experiment…
Multiphase unsteady Stokes flow over grooved surfaces: an analytical study
Yixuan Li, Karim Alame, Krishnan Mahesh
This paper studies multiphase flow within grooved textures exposed to external unsteadiness. We derive analytical expressions for multiphase unsteady Stokes flow driven by oscillat…
Wall-bounded flow over a realistically rough superhydrophobic surface
Karim Alamé, Krishnan Mahesh
Direct numerical simulations (DNS) are performed for two wall-bounded flow configurations: laminar Couette flow at and turbulent channel flow at , where is t…
