Response of a plate in turbulent channel flow: Analysis of fluid-solid coupling
Sreevatsa Anantharamu, Krishnan Mahesh
The paper performs simulation of a rectangular plate excited by turbulent channel flow at friction Reynolds numbers of 180 and 400. The fluid-structure interaction is assumed to be…
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…
A parallel and streaming Dynamic Mode Decomposition algorithm with finite precision error analysis for large data
Sreevatsa Anantharamu, Krishnan Mahesh
A novel technique based on the Full Orthogonalization Arnoldi (FOA) is proposed to perform Dynamic Mode Decomposition (DMD) for a sequence of snapshots. A modification to FOA is pr…
