Fig. 2.

Comparison of continuum and DES modeling of the bacterial growth. Shown are time traces of the amplitudes of density (A), velocity gradient (B), order parameter (C), and stress components for constant growth rate (D) (A = 2.0; models A and C1) and pressure-dependent growth rate (A = 4.0; models B and C2). Results of the continuum modeling are indicated by lines, and results of the DES simulations are indicated by symbols. Parameters of continuum models A and B are: L = 1, P = 10, s = 0.4, ρ_c^d = 0.62, ρ_c⁰ = 0.7, B = 1, μ = 8, α₀ = 1, p_c = 1.6.
