| Abstract:The CONVERGE software was implemented to establish an impinging spray flame transient heat transfer model based on conjugate heat transfer technology. The simulation model of transient heat transfer was calibrated with experimental data. This model was employed to investigate the effects of the distance to the wall， the injection pressure and the ambient oxygen volume fraction on the transient heat transfer characteristics of the impinging flame. The simulation results show that the change of the impingement distance has little effect on the wall heat transfer. The increase of the injection pressure and the increase of the ambient oxygen volume fraction will increase the transient wall heat transfer loss of the impinging spray flame. |
