Modules

module  m_reactive_burn
 Condensed-phase reactive burn: a pressure-driven programmed-burn source that converts a "reactant" fluid into a "product" fluid on the multi-fluid model (num_fluids=2, chemistry='F'). The two fluids share the same stiffened-gas EOS (gamma, pi_inf) and differ only in their reference energy qv, so the reactant->product conversion releases (qv_reactant - qv_product) per unit mass through the mixture EOS with no explicit energy source. Because the two fluids are mechanically identical the volume-fraction swap is exact (the product volume fraction is the reaction progress), making this a reactive-Euler/ZND detonation model expressed through the diffuse-interface framework. A shock raises the pressure above rburnpign, the reactant burns, and the energy release sustains the shock – a self-propagating condensed-phase detonation.

Functions/Subroutines

subroutine, public m_reactive_burn::s_compute_reactive_burn (rhs_vf, q_cons_vf, q_prim_vf, bounds)
 Add the programmed-burn reaction source to the continuity and volume-fraction RHS.
