Numerical study of cavitation regimes in flow over a circular cylinder
Filipe L. Brandao, Mrugank Bhatt, Krishnan Mahesh
Cavitating flow over a circular cylinder is investigated over a range of cavitation numbers for both laminar and turbulent regimes. We observe non-cavitating, cyclic and transition…
Analysis of wall-pressure fluctuation sources from DNS of turbulent channel flow
Sreevatsa Anantharamu, Krishnan Mahesh
The sources of wall-pressure fluctuations in turbulent channel flow are studied using a novel framework. The wall-pressure power spectral density (PSD) is expressed a…
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…
