Implicit-explicit all-speed schemes for compressible Cahn-Hilliard-Navier-Stokes equations
Andreu Martorell, Pep Mulet, Dionisio F. Yáñez
We propose a second-order implicit-explicit (IMEX) time-stepping scheme for the isentropic, compressible Cahn-Hilliard-Navier-Stokes equations in the low Mach number regime. The me…

A Variable-Slope Smooth- Filter for Modeling Halo Abundances with Damped and Oscillatory Power Spectra
Andreu Rocamora Martorell
We introduce a variable-slope smooth- (VSMK) filter within the Press-Schechter formalism to model halo mass functions derived from damped and oscillatory matter power spectra. W…

Implicit-explicit schemes for compressible Cahn-Hilliard-Navier-Stokes equations on staggered grids
Andreu Martorell, Pep Mulet, Dionisio F. Yáñez
We propose a second-order implicit-explicit (IMEX) time-stepping scheme for the isentropic, compressible Cahn-Hilliard-Navier-Stokes equations discretized on staggered (MAC) grids.…
