The non-dimensional dissipation rate \ud835\udc36\ud835\udf00 increases rapidly toward the final stage of the transition period of decay and the profile agrees well with previous direct numerical simulation [W. D. McComb et al., \u201cTaylor\u0027s (1935) dissipation surrogate reinterpreted,\u201d Phys. Fluids 22, 061704 (2010)] and theoretical estimation [D. Lohse, \u201cCrossover from high to low Reynolds number turbulence,\u201d Phys. Rev. Lett. 73, 3223 (1994)] at very low \ud835\udc45\ud835\udc52\ud835\udf06 in decaying and stationary isotropic turbulence. The present result of \ud835\udc36\ud835\udf00 is an update on the experimental data in grid turbulence toward a very low \ud835\udc45\ud835\udc52\ud835\udf06, where measurements have been absent. The energy spectrum in the dissipation range at very low \ud835\udc45\ud835\udc52\ud835\udf06 deviates from a universal form observed at high Reynolds numbers. The decay rate of enstrophy is proportional to \ud835\udc46+2\ud835\udc3a/\ud835\udc45\ud835\udc52\ud835\udf06 (S is the skewness of the longitudinal velocity derivative and G is the destruction coefficient). It is shown that G and \ud835\udc46+2\ud835\udc3a/\ud835\udc45\ud835\udc52\ud835\udf06 increase rapidly with decreasing \ud835\udc45\ud835\udc52\ud835\udf06 at very low \ud835\udc45\ud835\udc52\ud835\udf06, indicating that the effect of enstrophy destruction is dominant in the final stage of the transition period of decay. The profiles of \ud835\udc46+2\ud835\udc3a/\ud835\udc45\ud835\udc52\ud835\udf06 against \ud835\udc45\ud835\udc52\ud835\udf06 is well fitted by a power-law function even in the final stage of the transition period of decay.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "AIP Publishing", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "\u95a2\u9023\u60c5\u5831", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1063/5.0041929", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright 2021 Author(s).
