large eddy simulation of turbulent channel flows by the rational large eddy simulation model
(AIP Publishing, 2003-10)
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade) approximation of the Fourier transform of the Gaussian ...
Transfer function approach to output specification in certain linear distributed parameter systems
(American Institute of Mathematical Sciences, 2003)
We carry out error estimation of a class of immersed finite element (IFE) methods for elliptic interface problems with both perfect and imperfect interface jump conditions. A key feature of these methods is that their ...
Robust optimal switching control for nonlinear systems
(Siam Publications, 2002-09)
We formulate a robust optimal control problem for a general nonlinear system with finitely many admissible control settings and with costs assigned to switching of controls. e formulate the problem both in an L-2-gain/dissipative ...
Analysis and approximation of the velocity tracking problem for Navier-Stokes flows with distributed control
(Siam Publications, 2000-05)
We consider the mathematical formulation, analysis, and the numerical solution of a time-dependent optimal control problem associated with the tracking of the velocity of a Navier-Stokes ow in a bounded two-dimensional ...
