Complex-time singular structure of the 1D Hou-Luo model
Cornelius Rampf, Sai Swetha Venkata Kolluru
Starting from smooth initial data, we investigate the complex-time analytic structure of the one-dimensional Hou--Luo (HL) model, a wall approximation of the three-dimensional axis…
Early-time resonances in the three-dimensional wall-bounded axisymmetric Euler and related equations
Sai Swetha Venkata Kolluru, Rahul Pandit
We investigate the complex-time analytic structure of solutions of the 3D-axisymmetric, wall-bounded, incompressible Euler equations, by starting with the initial data proposed in…
Novel spectral methods for shock capturing and the removal of tygers in computational fluid dynamics
Sai Swetha Venkata Kolluru, Nicolas Besse, Rahul Pandit
Spectral methods yield numerical solutions of the Galerkin-truncated versions of nonlinear partial differential equations involved especially in fluid dynamics. In the presence of…
Insights from a pseudospectral study of a potentially singular solution of the three-dimensional axisymmetric incompressible Euler equation
Sai Swetha Venkata Kolluru, Puneet Sharma, Rahul Pandit
We develop a Fourier-Chebyshev pseudospectral direct numerical simulation (DNS) to examine a potentially singular solution of the radially bounded, three-dimensional (3D), axisymme…
