Acoustic Equation in a Lossy Medium
Tapan K. Sengupta, Prasannabalaji Sundaram, Aditi Sengupta
Here, the acoustic equation for a lossy medium is derived from the first principle from the linearized compressible Navier-Stokes equation without Stokes' hypothesis. The dispersio…
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…
Ultrasound Triggering of Rayleigh-Taylor Instability: Solution of Compressible Navier-Stokes Equation by a Non-Overlapping Parallel Compact Scheme
Prasannabalaji Sundaram, Aditi Sengupta, Tapan K. Sengupta
Rayleigh-Taylor instability (RTI) occurs at the interface of two media when the heavier fluid is accelerated into the lighter fluid and is a prototypical hydrodynamic event present…
