A microgroove evaporator is expected to realize a high heat transfer coefficient despite its simple structure. However, the thermal transport properties cannot be predicted from the groove structure, so far. In this research, we propose the revised numerical simulation model for predicting these properties by assuming a one-dimensional flow along the axial direction of grooves. Moreover the calculated meniscus profiles at the cross section of groove are validated by comparing the calculated profiles and the microphotos of meniscus profiles. The calculated meniscus profiles have shown good agreement with the experimental microscopic observation. The effects of the groove width on the calculated capillary length and rate of transported heat have also been discussed.
