Velocity and temperature fluctuations developed in the mixing layer were measured by a hotwire thermo-anemometer. Spectral components of these fluctuations satisfied the requirement for three-wave resonant interaction and the phase difference between the vertical component of the velocity fluctuation and the temperature fluctuation approached -pi/2 in the downstream region. These facts show that internal gravity waves are spontaneously generated in the mixing layer. It was also attempted to control the transition process of the internal gravity wave by giving a small thermal disturbance by installing a heated wire of 10 micrometer in diameter just behind the thermal stratification generator. The energy density levels of the spectral components increased downstream more rapidly in the mixing layer, which confirms the possibility of controlling the transition process of the internal gravity wave by the present method.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
