Contributed by the Heat Transfer Division of ASME for publication in the JOURNAL OF THERMAL SCIENCE AND ENGINEERING APPLICATIONS. Manuscript received September 24, 2014; final manuscript received March 13, 2015; published online May 12, 2015. Assoc. Editor: Zahid Ayub.

J. Thermal Sci. Eng. Appl 7(3), 031012 (Sep 01, 2015) (9 pages) Paper No: TSEA-14-1223; doi: 10.1115/1.4030104 History: Received September 24, 2014; Revised March 13, 2015; Online May 12, 2015

An experimental investigation on the heat transfer performance and pressure drop characteristics of thermally developing and hydrodynamically developed laminar flow of de-ionized (DI) water and 0.1%, 0.5%, and 0.8% concentrations of Al2O3/water nanofluid in wavy and straight minichannels was conducted. Reynolds number was varied from 700 to 1900 and two different heat fluxes of 45 kW/m2 and 65 kW/m2 were applied. The performance factor (PF) of water in wavy minichannels over their straight counterparts was higher than the nanofluids. Temperature distributions and general correlations of these minichannels are also presented.
