) is selected. The value of Ms can also be related to the gain margin (GM) and phase margin (PM) as GM≥Ms/(Ms-1), PM≥2sin-1(1/2Ms) [27]. Example 1: Consider an unstable first order plus dead time (UFOPDT......
flow inside an annulus filled with porous medium under the influence of entropy generation effect using Darcy-Brinkman- Forchheimer using two-phase mixture model. From their investigation... the frictional entropy generation and decreases the thermal entropy generation process. SIAVASHI et al [2] discussed the free convection flow and heat transfer characteristics of double diffusive two-phase......
