• Abstract : Channel/pipe flows mathematically modeled by the Navier-Stokes equation can be stabilized or destabilized by a slight viscosity stratification. We perform linear stability analysis (LSA) and non-linear simulation (NLS) for such flow, where a reaction changes the viscosity. The analysis involves a WENO-based diffuse-interface method for NLS and the Chebyshev spectral method for LSA. This talk will discuss how varying parameters representing the physical forces present in the system can control flow instabilities.
