The problem is relevant in connection with the counterflow burners used in laboratory experiments to characterize flame response to strain. The computation of the inviscid flow involves integration of the Euler equations, with the outer jet boundaries and the interface separating the two jets appearing as free surfaces, to be obtained as part of the solution. It is shown how introduction of a single density-weighted stream function facilitates the description. While conformal mapping can be used to determine the solution for irrotational flow, numerical integration is required in general, with simplified limiting solutions arising in the limiting cases H/R ! 1 and H/R " 1. 000014029 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014029 653__ $$a 000014029 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014029 720__ $$aWeiss, Adam 000014029 8560_ $$ffischerc@itam.cas.cz 000014029 8564_ $$s195070$$uhttps://invenio.itam.cas.cz/record/14029/files/PO.FM17-1.05.97.pdf$$yOriginal version of the author's contribution as presented on CD, XMLout( page 1651, code PO.FM17-1.05.97). 000014029 962__ $$r13812 000014029 980__ $$aPAPER
