Abstract
The effect of solid particles on the performance of oscillating flow heat pipe (O-HP) has been investigated using a loop O-HP plate. The O-HP plate was made of Al plate with 2×2 mm chase. A1203 nano-particles (30 nm diameter) were added into Ethanol as working fluid. Heat transfer performance of the O-HP was tested under concentration of 0-3.0 wt% for Al2O3 nano-fluid at volume filling ratio of 50%. Experimental results show that the nano-fluid tends to slightly enhance the heat transfer performance of the O-HP under high heat load condition. However, the heat transfer performance decreased as the nano-particles settled out after repeating the test.
