摘要：

Due to the presence of large interfaces, heat transfer can be enhanced by the vortices in liquid plugs in microchannel heat exchangers. The heat transfer in liquid plugs moving in microcapillaries with constant-surface-heat-flux boundary condition is investigated. The effects of the Peclet number and the plug length are studied. Higher Peclet numbers and shorter plug length result in higher Nusselt numbers and lower maximum fluid temperature. However, higher Peclet numbers require higher flow speed, while shorter plug lengths result in higher flow resistance coefficients. The pressure drop needs to be considered in the optimization of microchannel heat exchangers. (C) 2012 Elsevier Masson SAS. All rights reserved.
