Local thermalization in our models occurs as the result of binary collisions among locally confined gas particles. We explore the conditions under which relaxation to local equilibrium, which involves no energy exchange, takes place on time scales shorter than that of the binary collisions which induce local thermalization. The role of this mechanism in multi-phase material systems such as aerogels is discussed.", "revisions": [ { "version": "v1", "updated": "2008-06-13T07:20:52.000Z" } ], "analyses": { "subjects": [ "05.20.Dd", "05.45.-a", "05.60.-k", "05.70.Ln" ], "keywords": [ "heat conduction", "fouriers law", "consecutive local mixing", "multi-step local thermalization mechanism", "binary collisions" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2008, "month": "Jul", "volume": 101, "number": 2, "pages": "020601" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvL.101b0601G" } } }
