Domain decomposition methods are widely used for the numerical solution of partial differential equations on high performance computers. We develop an adjoint-based a posteriori error analysis both multiplicative and additive overlapping Schwarz domain methods. The in user-specified functional (quantity interest) is decomposed into contributions that arise as result finite iteration between sub...
Studying the behaviour of supercavitation from the energy aspect can be divided into two sections. Studying the behavior of supercavitation in the flow field and in vicinity of the flow field. A large portion of field energy is kept in the field, and the rest of it distributed as noise (sound) out of the field. In this paper, harmonious structures of the field which are flowing as energy source...
Spatial coupling during catalytic ignition of CO oxidation on μm-sized Pt(hkl) domains of a polycrystalline Pt foil has been studied in situ by PEEM (photoemission electron microscopy) in the 10(-5) mbar pressure range. The same reaction has been examined under similar conditions by FIM (field ion microscopy) on nm-sized Pt(hkl) facets of a Pt nanotip. Proper orthogonal decomposition (POD) of t...
The creation of sound zones with frequency-domain variable span trade-off filters (VAST) is investigated herein. Both narrowband and broadband discrete Fourier transform (DFT)-domain VAST approaches are proposed, we discuss their relationship to the existing time-domain approach. core idea in apply a generalized eigenvalue decomposition spatial statistics control between acoustic contrast signa...
