Abstract

In the present paper, a laminar Counter-flow flame has been numerically investigated under the transcritical and supercritical conditions. The Cantera open source code has been used to calculate the flow field and the kinetic combustion solution. Furthermore, the energy equation, the thermodynamics and the transport properties have been modified for real gas solution. The thermodynamics properties, including density, enthalpy, and specific heat at constant pressure, are evaluated based on fundamental thermodynamics theories and the modified SRK equation of state (EOS). Transport properties, including thermal conductivity and dynamic viscosity, are estimated using Chung method. It can be seen that the pseudo-boiling phenomenon has been appeared in transcritical condition with real gas equations. The ideal gas solution is unable to capture this phenomenon. In the mixture fraction field, there is no major difference between the real gas and the ideal gas, which is important for solving the turbulent reacting flow by the flamelet models. However In the physical field, the difference between the real gas condition and the ideal gas is significant in terms of the position and dimensions of the flame for the transcritical state. For supercritical conditions in the physical field similar to mixture fraction field, there is no significant difference in the flame situation.
