Here, we present some interesting new results on the linear modal stability of Couette–Poiseuille flow (CPF), by numerically solving Orr–Sommerfeld equation within temporal framework. We provide a mechanistic explanation to well-known result that upper plate movement causes progressive stabilization CPF. The energy budget reveals appearance region negative production with movement, which is located near has higher relative velocity in direction bulk flow. This contribution integral term,...

The celebrated Curci-Ferrari (CF) type of restrictions are invoked to obtain the off-shell nilpotent and absolutely anticommuting (anti-) BRST as well co-BRST symmetry transformations in context Lagrangian description physical four (3 + 1)-dimensional (4D) free Abelian 2-form gauge theory. We show that above CF conditions, which turn out be secondary constraints theory, remain invariant with respect time-evolution system Hamiltonian formulation. This invariance (i) physically ensures linear...
