It includes a two-equation turbulence model for the major part of the benthic boundary layer and the interior, while a low Reynolds number one-equation turbulence model with prescribed length scale is applied to the viscous sublayer in order to resolve the latter layer. This because the main resistance in the transfer of a substance between the sediments and the benthic boundary layer is found in this sublayer. The flux rates are calculated by use of a diffusion equation where the vertical dependence of exchange coefficient is determined by the two turbulence models. The present model is limited to hydrodynamically smooth bottoms. The predicted flux rates are in good agreement with independent estimates of scalar fluxes from boundaries for both low and high Prandtl/Schmidt numbers. The time-dependent model also yields detailed concentration and velocity profiles together with turbulence parameters.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"On the mass transfer properties of the benthic boundary layer with an application to oxygen fluxes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2019-07-10","DateCreate":"2001-08-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1989CB25200004","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16023,"PubliDate":1989,"Pagination":"27-35","XtraPublOfAnaID":null,"ISBN":null,"Volume":"24","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
