Extraction of macroscopic and microscopic adjoint concepts using a lattice Boltzmann method and discrete adjoint approach.

摘要: In the present research, we tried to improve performance of lattice Boltzmann (LB) -based adjoint approach by utilizing mesoscopic inherent LB method. this regard, two macroscopic discrete (MADA) and microscopic (MIDA) approaches are used answer following challenging questions. Is it possible extend concept variables flow field corresponding ones? Further, similar conservative laws in method, is find comparable conservation equations approach? If so, then a definite framework, that solution can be employed sensitivity analysis MIDA approach. This achievement decrease implementation cost coding efforts method complicated problems. First, MADA extracted based on using duality viewpoint. Meanwhile, an elementary case, inverse design two-dimensional unsteady Poiseuille periodic channel with constant body forces, procedure analytical evaluation described. The numerical results show correlations between distribution functions seen ones. Besides, promising, emphasizing evaluated via functions. Finally, introduced.
