Sodium and watrer experiments on thermal striping phenomena were carried out. Triple-parallel jet along a wall was investigated. Further, quasi-DNS was also performed and comparisons between experiments and analyses were carried out. Temperature fluctuation intensity near the wall was larger in water than in sodium. This means that water experiment can predict sodium temperature fluctuation intensity with certain conservative factor.
