  • experimental study on laminar convective heat transfer of microencapsulated phase change material slurry using liquid metal with low melting point as Carrying Fluid
    International Journal of Heat and Mass Transfer, 2014
    Co-Authors: Sihong Song, Weidong Shen, Jianli Wang, Shengchun Wang, Jiafeng Xu
    Abstract:

    Abstract The microencapsulated phase change material slurry using liquid metal with low melting point as Carrying Fluid (MEPCM-LM slurry) is a novel and powerful cooling Fluid applied in thermal management of high power electronic devices. The laminar convective heat transfer performances of MEPCM-LM slurry in a tube with constant heat flux were investigated experimentally. The effects of MEPCM volume concentration, Re and heat rate on heat transfer characteristics were also studied. Results indicate that the Fanning friction factor of MEPCM-LM slurry d is in good accord with the theoretic values (f = 16/Re), and the MEPCM-LM slurry can be considered as Newton Fluid. It is also found that the modified local convective heat transfer coefficient ( h x ∗ ) for MEPCM-LM slurry is higher than that for pure gallium. Furthermore, the h x ∗ increases with increasing volume concentration and Re. The h x ∗ increases with increasing the heat rate before phase change finished and the variation trend of h x ∗ with heat rate is contrary after phase change finished, but the h x ∗ is not much influenced by the imposed heat fluxes tested. The kind of MEPCM-LM slurry has good application future in practice.

  • numerical study on laminar convective heat transfer enhancement of microencapsulated phase change material slurry using liquid metal with low melting point as Carrying Fluid
    International Journal of Heat and Mass Transfer, 2013
    Co-Authors: Sihong Song, Yu Ruan, Weidong Shen, Qiang Liao, Jiafeng Xu
    Abstract:

    Abstract The laminar convective heat transfer enhancement of microencapsulated phase change material slurry using liquid metal with low melting point as Carrying Fluid (MEPCM-LM slurry) in a tube with constant heat flux has been investigated numerically. The influence of each factor affecting the heat transfer enhancement was analyzed in detail by using an effective specific heat capacity model and considering axial heat conduction to be not neglected. Furthermore, the heat transfer ability of MEPCM-LM slurry was compared with that of MEPCM slurry using water as Carrying Fluid (MEPCM-Water slurry). It is found that bulk Stefan number and MEPCM concentration are the most important parameters influencing the heat transfer enhancement of MEPCM-LM slurry. The degrees of heat transfer enhancement increase with decreasing bulk Stefan number, dimensionless initial supercooling and/or dimensionless phase change temperature range, and increase with increasing mass concentration. The peak of the degree of heat transfer enhancement decreases with increasing Re. Moreover, the heat transfer ability of MEPCM-LM slurry is better than that of MEPCM-Water slurry, and the difference of the heat transfer ability for two slurries increases with decreasing x / r 0 , therefore, it is more advantageous to heat dispersion of chip in narrow space for MEPCM-LM slurry.
