  2. 1. Numerical study of flow boiling in micro/mini channels

    Author : Qingming Liu; Björn Palm; Satish Kandlikar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical; boiling; micro channel; phase change.; Energiteknik; Energy Technology;

    Abstract : Boiling phenomena in micro scale has emerged as an interesting topic due to its complexity and increasing usage in micro electronic and mechanical systems (MEMS). Experimental visualization has discovered five main flow regimes: nucleate boiling, isolated bubbles, confine bubbly flow, elongated bubbly (or slug) flow, and annular flow. READ MORE
