On the an.lytical solution of tran.ient friction in chan.el flows

引用

Applied Mathematics an. Mechan.cs(English Edition) 2024年第8期45卷 1447-1466页

作者： F.J.garcíA-garcíA P.FARI?AS-ALVARI?O Department of Naval & Industrial Engineering Polytechnic School of EngineeringUniversity of A Coru?a Campus Industrial de Ferrol Integraciones Técnicas de Seguridad S.A. Pol.Ind.Espíritu Santo

The tran.ient friction in chan.el mean.flows is the sum of two contributions,i.e., the underlying laminar flow(ULF) an. the purely turbulent component(PTC), an. the contributions are an.lyzed separately by theoretical experiments. It is found that,the tran.ient friction may be higher or remarkably lower than.that in equal-Reynolds number steady-state flows. The universal time constan. for plan.-parallel laminar flows is reported, an. the role of the time constan. in a turbulent mean.flow is examined. It is shown that the time constan. is related to the turbulence's frozen time. Finally, a study of the logarithmic layer during the tran.ient flow is accomplished, which shows that the logarithmic layer is destroyed.

In this work,several ceria-zirconia based catalysts with very lo w（an. equimolar） metal contents were prepared,characterised an. tested for the CO oxidatio n reaction（under lean.an. stoichiometric conditions）,trying to emulate those conditions found in a diesel oxidation catalyst（DOC） system from a diesel engine an. those encountered under gasoline exhaust（λ=1）.The metals chosen are Cu,Co,Ag an. Pt（as a reliable benchmark）.The results reveal enormous differences among reducibility an. catalytic activity despite quite similar structural an. textural properties of the catalysts,showing differences among dispersion（Ag-catalyst seems to present a low level of dispersion）.This catalyst seems to be characterised,as well,by a strong electronic interaction between Ce an. Ag centres which is suggested to yield an.improved reducibility under H2-TPR ***,the order in catalytic activity（Cu>Ag>Co≈Pt>>support） seems not to follow the order found in reducibility an. the Cu-catalyst seems to be the most active independently on the reaction conditions,yielding nearly overlapped CO oxidation catalytic *** restingly,a stro ng correlation between the catalytic activity under the two conditions tested an. the osC values of the Ce0.8Zr0.2O2-supported metal catalysts is ***,osC parameter measured at 150℃ can.be used as a relevan. descriptor to evaluate the CO oxidation activity at low an. medium conversions for the investigated catalysts,much better than.the H2-TPR measurements.
