“…Among the open-source codes, the OpenFOAM library is a wellestablished open platform in the scientific community [29]. It is noteworthy that there are several in-house codes reported in the literature for high-speed compressible reacting flows [13,14,[30][31][32][33][34][35][36][37]. These codes have been used to solve many problems involving turbulence-combustion interactions.…”

An approach based on the OpenFOAM library has been developed to solve a high-speed, multicomponent mixture of a reacting, compressible flow. This work presents comprehensive validation of the newly developed solver, called compressibleCentralReactingFoam, with different supersonic flows, including shocks, expansion waves, and turbulence–combustion interaction. The comparisons of the simulation results with experimental and computational data confirm the fidelity of this solver for problems involving multicomponent high-speed reactive flows. The gas dynamics of turbulence–chemistry interaction are modeled using a partially stirred reactor formulation and provide promising results to better understand the complex physics involved in supersonic combustors. A time-scale analysis based on local Damköhler numbers reveals different regimes of turbulent combustion. In the core of the jet flow, the Damköhler number is relatively high, indicating that the reaction time scale is smaller than the turbulent mixing time scale. This means that the combustion is controlled by turbulent mixing. In the shear layer, where the heat release rate and the scalar dissipation rate have the highest value, the flame is stabilized due to finite rate chemistry with small Damköhler numbers and a limited fraction of fine structure. This solver allows three-dimensional gas dynamic simulation of high-speed multicomponent reactive flows relevant to practical combustion applications.

The general mathematical formulation of describing flows with chemical reactions problem includes mass conservation, momentum, energy and concentrations equations for each chemical substance, supplemented by the state equation and other thermodynamic relations. Chemical kinetics, through the heat of reactions, relates the concentrations of various substances to the energy equation. In many combustion systems, it is the chemical kinetics that determines the characteristic spatial and temporal scales of the equations to be solved. In this paper, we consider the problem of spray combustion of gaseous simple hydrocarbon fuel in a cylindrical channel. Mathematical modeling was carried out within the framework of the open package OpenFOAMv7, and the visualization of numerical results was carried out using Paraview 5.6. Deep understanding and tuning of a simple gaseous reaction scheme in the OpenFOAM package when modeling reacting flows is the goal of this work. It is shown that the CFD package used makes it possible to successfully simulate this class of flows.
