| Abstract: | In the present work the effect of addition of nanoclay particles having concentrations of 0.001, 0.01 and 0.1 vol% on cooling performance of water during immersion quenching was investigated. Cooling curve analyses were carried out by using standard ISO/DIS 9950 quench probe. Wetting behavior of nanoquenchant was studied using dynamic contact angle analyzer. The spreading behavior of droplets of quench media on INCONEL 600 substrate indicates improved wetting behavior of nanofluids. The peak cooling rate and cooling rate at 700�C for water decreased by addition of nanoparticles. Further, quenching in nanofluid shows longer vapour blanket stage as compared to water. The estimated flux transients and Grossmann H factor clearly show that decreased cooling performance of water by addition of nanoparticles. Copyright � 2012 ASM International� All rights reserved. |
