摘要：

In this work, the nanofluid flow inside a microchannel with serrated injection jet on the upper wall of microchannel and using magnetic field with intensity of 0–40 Hartman were surveyed. The lower microchannel wall with jet injection racks has a constant temperature, but the upper microchannel wall is insulated among injection jets. Applying dented mode for injection jets was performed to enhance heat transfer. This research was performed for Reynolds numbers 10–50 and B = 0.01, 0.05, and 0.1 and for volume fraction of 0–6% water/Al2O3. The results indicated that the higher the height of dents was, the higher the heat transfer occurred.
