摘       要:

       This study proposes a novel addition of rigid fflamentous tail structure at the trailing edge of the ribs to enhance the heat transfer performance of ffow boiling in mini-channel under rolling conditions. The ffow boiling heat transfer characteristics of Novec649 in both rib-channel and rigid-tail rib-channel are experimentally investigated. Heat ffux, inlet ffow velocity, rolling angle and rolling period are considered as the variable parameters, which are 50 – 300 kW⋅m− 2 , 0.3 – 0.9 m⋅s − 1 , 0 – 15◦, 10 – 20 s, respectively. The experimental results show that the rigid-tail structure improves the heat transfer performance of the channels within the entire range of thermal parameters, while increasing the pressure drop at high heat ffux and/or high velocity. Compared with ribchannel, the rigid-tail structure exhibits the strongest enhancement in ffow boiling heat transfer performance under high heat ffux of qeff = 300 kW⋅m− 2 and high ffow velocity of vin = 0.9 m⋅s − 1 , and the heat transfer coefffcient can be increased by 6.93 % at most. And increasing the rolling angle or decreasing the rolling period will decrease the average wall temperature by a maximum of 1.94 ◦C and increase the heat transfer performance factor j by a maximum of 8 % at vin = 0.3 m⋅s − 1 , qeff = 200 – 300 kW⋅m− 2 for the rigid-tail rib-channel. Furthermore, the addition of a rigid-tail structure helps maintain smaller bubble sizes and a more uniform distribution in the mainstream region of the two-phase ffow.
