Experimental research on heat transfer characteristics of the unstable multi-hole steam jets and development of the lumped condensation model

•The intense temperature and plumes variations in multi-hole unstable condensation are analyzed.•The preliminary double-hole condensation flow regimes map is firstly developed.•The simplified lumped condensation model for the multi-hole steam jets is proposed.•The HTC ranges in the multi-hole unstab...
