Effects of overburden pressure on granular shear flows: Multiplicity and chaos

The file contains data corresponding to all the figures included in the article. Each sheet presents the data for a specific figure. The profiles of scaled mean velocity, solid volume fraction, and scaled fluctuating velocity are shown across the domain (scaled height) for various wall velocities, overburden pressures (fig2), stiffness constants (fig3), and different configurations (fig6). The scaling of midplane velocity with wall velocity for various overburden pressures is provided in Sheet fig4. Sheet fig5 shows the variation of scaled midplane velocity with scaled overburden pressure for different wall velocities, stiffness constants, and coefficients of friction. Transient profiles of mean velocity, solid fraction, and fluctuating velocity showing the system's transition from a stable plug in the lower region to the top (fig7), and plug fluctuations under intermediate pressures (fig8), are shown across the domain for the Parallel case. The midplane velocity over time for the Parallel case is shown in Sheet fig9a, with its corresponding power spectral density (PSD) data in Sheet fig9b, alongside the PSD of midplane velocity in the fixed wall case and wall fluctuations in the normal direction. Sheet fig10 displays the PSD for various overburden pressures in the Parallel case. Midplane velocity distributions for various wall velocities and overburden pressures are shown in Sheet fig11 for the Parallel case, followed by their standard deviations in Sheet fig12 and the effects of the coefficient of friction on standard deviation are shown in Sheet fig13.
