This paper investigates the linear and nonlinear dynamics of two-dimensional penetrative convection subjected to radiative volumetric thermal forcing, focusing on ice-covered freshwater systems. Linear stability analysis reveals how critical wavenumbers $k_c$ Rayleigh numbers $Ra_c$ are influenced by attenuation lengths incoming heat flux. In this configuration, system easily becomes unstable with a small , which is two decades smaller than that classical Rayleigh–Bénard problem, typically...
Abstract An unstably stratified flow entering into a stably is referred to as penetrative convection, which crucial many physical processes and has been thought of key factor for extreme weather conditions. Past theoretical, numerical, experimental studies on convection are reviewed, along with field providing insights turbulence modeling. The factors that initiate including internal heat sources, nonlinear constitutive relationships, centrifugal forces other complicated summarized....
