Two-dimensional planar nitrogen jets under supercritical pressures are simulated in order to clarify its unique characteristics. The present study covers two supercritical pressures of 4 MPa and 8 MPa and three jet temperatures between a cryogenic jet of about 80 K and a warmer jet of 133 K. A unique characteristic is found in both the mean temperature and the temperature fluctuation distributions only in case of a near-critical pressure of 4 MPa and a cryogenic jet of 80 K. The specific heat distributions clearly explain the generation of the unique temperature distributions, i.e., slower increase of jet temperature and relatively weak fluctuation of temperature in the downstream region. The other conditions, including a low-temperature jet of 126 K, show no major differences.
