CO Oxidation over Alumina-Supported Copper Catalysts
Ma, Guoyan; Wang, Le; Wang, Xiaorong; Li, Lu; Ma, Hongfei (Peer reviewed; Journal article, 2022)CO oxidation, one of the most important chemical reactions, has been commonly studied in both academia and the industry. It is one good probe reaction in the fields of surface science and heterogeneous catalysis, by which ... -
Energy-preserving numerical methods for differential equations: Linearly implicit methods and Krylov subspace methods
Li, Lu (Doctoral theses at NTNU;2019:272, Doctoral thesis, 2019) -
Krylov projection methods for linear Hamiltonian systems
Li, Lu; Celledoni, Elena (Journal article; Peer reviewed, 2019)We study geometric properties of Krylov projection methods for large and sparse linear Hamiltonian systems. We consider in particular energy-preservation. We discuss the connection to structure preserving model reduction. ... -
Linearly implicit local and global energy-preserving methods for Hamiltonian PDEs
Eidnes, Sølve; Li, Lu (Journal article, 2019)We present linearly implicit methods that preserve discrete approximations to local and global energy conservation laws for multi-symplectic PDEs with cubic invariants. The methods are tested on the one-dimensional Korteweg–de ... -
Linearly implicit structure-preserving schemes for Hamiltonian systems
Eidnes, Sølve; Li, Lu; Sato, Shun (Journal article, 2019)Kahan’s method and a two-step generalization of the discrete gradient method are both linearly implicit methods that can preserve a modified energy for Hamiltonian systems with a cubic Hamiltonian. These methods are here ...
