“…Further details on the algorithm implemented to automate the aforementioned solution procedure and on the existence of solutions without a sonic point are included in the work of Mejía-Botero et al [27]. Our solver has been used in the past to study detonations with curvature [31][32][33] and friction [27] losses. The ability of the model and the solver to estimate detonability limits was assessed by Mejía-Botero et al [34], showing that it is in reasonable agreement with experimental data.…”

The effect of heat and momentum losses on the steady solutions admitted by the reactive Euler equations with sink/source terms is examined for stoichiometric hydrogen–oxygen mixtures. Varying degrees of nitrogen and argon dilution are considered in order to access a wide range of effective activation energies, $$E_{\textrm{a,eff}}/R_{\textrm{u}}T_{0}$$ E a,eff / R u T 0 , when using detailed thermochemistry. The main results of the study are discussed via detonation velocity-friction coefficient (D–$$c_{\textrm{f}}$$ c f ) curves. The influence of the mixture composition is assessed, and classical scaling for the prediction of the velocity deficits, $$D(c_{\textrm{f,crit}})/D_{\textrm{CJ}}$$ D ( c f,crit ) / D CJ , as a function of the effective activation energy, $${E}_{\textrm{a,eff}}/R_{\textrm{u}} T_{0}$$ E a,eff / R u T 0 , is revisited. Notably, a map outlining the regions where set-valued solutions exist in the $$E_{\textrm{a,eff}}/R_{\textrm{u}}T_{0}\text {--}{\alpha }$$ E a,eff / R u T 0 -- α space is provided, with $$\alpha $$ α denoting the momentum–heat loss similarity factor, a free parameter in the current study.
