Abstract: High-Rayleigh-number ( $Ra$ ) convection in an inclined two-dimensional porous layer is investigated using direct numerical simulations (DNS) and stability and variational upper-bound analyses. When the inclination angle $\unicode[STIX]{x1D719}$ of the layer satisfies $0^{\circ }\unicode[STIX]{x1D719}_{t}$… read more here.

DOI: 10.1017/jfm.2018.139
Abstract: The kinematics of a fully developed passive scalar is modelled using the hierarchical random additive process (HRAP) formalism. Here, ‘a fully developed passive scalar’ refers to a scalar field whose instantaneous fluctuations are statistically stationary,… read more here.

DOI: 10.1017/jfm.2019.257
Abstract: We report an experimental study of the distributions of temperature and solid fraction of growing $\text{NH}_{4}\text{Cl}$ – $\text{H}_{2}\text{O}$ mushy layers that are subjected to periodical cooling from below, focusing on late-time dynamics where the mushy… read more here.
