Bifurcation sequence of two-dimensional Taylor-Green vortex via vortex interactions: Evolution of energy spectrum
Tapan K. Sengupta, Ankan Sarkar, Bhavna Joshi +2
The vorticity dynamics of the two-dimensional (2D) Taylor-Green vortex (TGV) problem is investigated in its multi-cellular configuration by solving the incompressible Navier-Stokes…
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…
Equation for Aeroacoustics in a Quiescent Environment
Tapan K. Sengupta, Aditi Sengupta, Bhavna Joshi
The perturbation equation for aeroacoustics has been derived in a dissipative medium from the linearized compressible Navier-Stokes equation without any assumption, by expressing t…
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…
