The shape characteristics and direct contact condensation (DCC) heat transfer of submerged supersonic steam jet were investigated. One of the shape identification methods is the DCC shape regime map as a function of nozzle exit pressure, mass flux and pool water temperature, another one is the Look Up Table. Then based on the theoretical analysis, the new basic expressions of supersonic steam jet dimensionless penetration length, maximum expansion ratio, and heat transfer correlations were given, which were in terms of Ma number and Ja number. The correlations were nonlinearly fitted and validated well against the experimental data form open literatures. The discrepancies of penetration length and maximum expansion ratio between predicted and experimental values were within ±25% and ±12% respectively. Supersonic steam jet DCC heat transfer is feasible to be calculated via the identification of steam jet shape and selection of the corresponding shape and heat transfer correlations.
