Kurzfassung
Motivated by laminarization problems in fully turbulent airfoil computations, the low Reynolds differential Reynolds stress model of Jakirli\'c and Hanjali\'c (Jakirli\'c et al., 2007) is investigated in the model problem of homogeneous shear flow. An investigation of the fixed point properties of this equation system is presented along with an analysis of phase space trajectories. From this analysis, factors are identified that promote convergence towards degenerate solutions and could serve as a starting point for model improvements.
