The two passive scalars are convected by the identical turbulence but excited by the different scalar injections. It is found that all the exponents have plateaus at separation distance in between twice the Taylor microscale and a quarter of the integral scale, for which the inertial range is defined and does not coincide with the −5/3 kinetic energy spectrum range. The crossover lengths of the inertial (convective) and the dissipation (diffusive) ranges are found to be independent of the order of the structure functions. 000014740 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014740 653__ $$a 000014740 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014740 720__ $$aGotoh, Toshiyuki 000014740 8560_ $$ffischerc@itam.cas.cz 000014740 8564_ $$s275979$$uhttp://invenio.itam.cas.cz/record/14740/files/TS.FM14-4.03.pdf$$yOriginal version of the author's contribution as presented on CD, page 1433, code TS.FM14-4.03 . 000014740 962__ $$r13812 000014740 980__ $$aPAPER
