WebIn this work, a three-phases discrete dynamic model of column flotation which accounts for the interface and froth regions is developed. The system is described by transport hyperbolic nonlinear partial differential equations (PDEs). The steady state profiles are utilized to linearize the original nonlinear system.

LINEARIZATION OF PDEs - INSPIRE-HEP

WebIf we linearize about u 0 = 1, we get a different result. Setting u= 1+ wgives w t = w xx w 2w2; so that the linearization is now w t = w xx w: (14) This equation has a dispersion relation ˙= k2 1, which is always negative. Thus any initial condition of the form u(x;0) = 1+ w(x;0) in the original equation should evolve in time in a way Web16 feb. 2024 · Answers (2) Sulaymon Eshkabilov on 15 Feb 2024.
