Rolling amplitude
WebFeb 24, 2011 · The effects of rolling and pitching motions on turbulent heat transfer are investigated. The time averaged Reynolds number and the fluctuation-velocity Reynolds number are 40,000 and 2,000, respectively. The rolling amplitude is 15° and the rolling period is 10 s. The heat flux is 200 kw/m 2. The calculation results are listed in Fig. 13. WebOct 20, 2024 · Rolling motion caused by ocean condition will induce more complicated inertial forces with their force directions changing all the time, which results more complex bubble behaviors and unique heat transfer characteristics.
