Fourth order compact scheme for the Navier-Stokes equations on time deformable domains
Shuvam Sen, Tony W. H. Sheu
In this work, we report the development of a spatially fourth order temporally second order compact scheme for incompressible Navier-Stokes (N-S) equations in time-varying domain.…

Phase error analysis of implicit Runge-Kutta methods: Introducing new classes of minimal dissipation low dispersion high order schemes
Subhajit Giri, Shuvam Sen
In current research, we analyse dissipation and dispersion characteristics of most accurate two and three stage Gauss-Legendre implicit Runge-Kutta (R-K) methods. These methods, kn…
