Cement paste, a major component of concrete, is a porous medium with a complicated three-dimensional geometry. The structure of the model concrete was selected on the basis of experimental data obtained by high-intensity X-ray computed tomography. The LKS, an improved version of the original lattice Boltzmann method, was used to save computational memory and to maintain numerical stability. First, an unsteady convection-diffusion problem was examined, and the accuracy of the method and the error norms with various lattice resolutions were investigated. Next, the problem of the calcium current in concrete was simulated. Pressure drops in the concrete were calculated for various Reynolds numbers, and the results were compared with those of an empirical equation based on experimental data. Also, velocity fields and concentration profiles were obtained at a pore scale for a structure with inhomogeneous mass diffusivities. These simulations showed that the present method might be useful for predicting calcium leaching in concrete from the microscopic point of view.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Fluid Science and Technology. 4(1):13-24 (2009)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Yoshino, M","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ONkpbpkh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1299/jfst.4.13"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1299/jfst.4.13","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-5558","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yoshino,  M"}],"nameIdentifiers":[{"nameIdentifier":"38460","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Murayama,  T"}],"nameIdentifiers":[{"nameIdentifier":"38461","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuzaki,  A"}],"nameIdentifiers":[{"nameIdentifier":"38462","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi,  H"}],"nameIdentifiers":[{"nameIdentifier":"38463","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"yoshino_simulation_lattice_kinetic.pdf","filesize":[{"value":"5.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"yoshino_simulation_lattice_kinetic.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/12578/files/yoshino_simulation_lattice_kinetic.pdf"},"version_id":"22b5fa97-c3e4-4055-9953-86bff0c7f8f9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Simulation of Mass Transfer of Calcium in Concrete by the Lattice Kinetic Scheme for a Binary Miscible Fluid Mixture","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simulation of Mass Transfer of Calcium in Concrete by the Lattice Kinetic Scheme for a Binary Miscible Fluid Mixture","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1222"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-05-20"},"publish_date":"2009-05-20","publish_status":"0","recid":"12578","relation_version_is_last":true,"title":["Simulation of Mass Transfer of Calcium in Concrete by the Lattice Kinetic Scheme for a Binary Miscible Fluid Mixture"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:30:18.945579+00:00"}
