Perturbation Field in The Presence of Uniform Mean Flow: Doppler Effect for Flows and Acoustics
Tapan K. Sengupta, Aditi Sengupta, Bhavna Joshi +1
Having developed the perturbation equation for a dissipative quiescent medium for planar propagation using the linearized compressible Navier-Stokes equation without the Stokes' hy…
Evolution of Perturbation in Quiescent Medium
Tapan K. Sengupta, Shivam K. Jha, Aditi Sengupta +2
Here, the perturbation equation for a dissipative medium is derived from the first principle from the linearized compressible Navier-Stokes equation without Stokes's hypothesis. Th…
Determining Parameter Ranges for High Accuracy Large Eddy Simulation by Lax-Wendroff Method
V. K. Suman, Soumyo Sengupta, P. Sundaram +2
The analysis of Lax-Wendroff (LW) method is performed by the generic modified differential equation (MDE) approach in the spectral plane using Fourier transform. In this approach,…
Quantifying Resolutions for DNS and LES for Lax-Wendroff Method: Application to Uniform/Non-Uniform Compact Schemes
V. K. Suman, P. Sundaram, Soumyo Sengupta +2
The global spectral analysis (GSA) of numerical methods ensures that the dispersion relation preserving (DRP) property is calibrated in addition to ensuring numerical stability, as…
A linear dispersive mechanism for numerical error growth: spurious caustics
Claire David, Pierre Sagaut, Tapan Sengupta
A linear dispersive mechanism for error focusing in polychromatic solutions is identified. This local error pile-up corresponds to the existence of spurious caustics, which are all…
