The effects of radiative heat transfer in arc-heated nonequilibrium flow simulation

摘要: Numerical simulation of a 20 kW constrictor-type arc-heated flow was carried out, and the distribution nonequilibrium flow-field properties obtained. The field described by Navier–Stokes equations with multi-temperature model, tightly coupled electric-field radiation-field calculations. As radiation an accurate low-cost model introduced into simulation. It confirmed that plasma inside facility is in state high arc discharge plays critical role. By comparing computational results with/without it clarified exerts significant effects on heat transport constrictor section. Additionally, to validate present numerical solutions were compared experimental data. indicated tends be good agreement corresponding
