@article{(Open Science Index):https://publications.waset.org/pdf/10002313, title = {Second-Order Slip Flow and Heat Transfer in a Long Isothermal Microchannel}, author = {Huei Chu Weng and Chien-Hung Liu}, country = {}, institution = {}, abstract = {This paper presents a study on the effect of second-order slip and jump on forced convection through a long isothermally heated or cooled planar microchannel. The fully developed solutions of thermal flow fields are analytically obtained on the basis of the second-order Maxwell-Burnett slip and Smoluchowski jump boundary conditions. Results reveal that the second-order term in the Karniadakis slip boundary condition is found to contribute a negative velocity slip and then to lead to a higher pressure drop as well as a higher fluid temperature for the heated-wall case or to a lower fluid temperature for the cooled-wall case. These findings are contrary to predictions made by the Deissler model. In addition, the role of second-order slip becomes more significant when the Knudsen number increases.}, journal = {International Journal of Aerospace and Mechanical Engineering}, volume = {9}, number = {7}, year = {2015}, pages = {1348 - 1351}, ee = {https://publications.waset.org/pdf/10002313}, url = {https://publications.waset.org/vol/103}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 103, 2015}, }
