Visualization of Quench Front Propagation on Heated Rod Through Single Jet ImpingementSource: Journal of Heat Transfer:;2020:;volume( 142 ):;issue: 009::page 092301-1DOI: 10.1115/1.4047149Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quench front characteristics and flow physics have been observed for single jet impingement using de-ionized (DI) water and various oxide-based nanofluids. Quench front velocity, shape, intensities of sputtering, and postquench front phenomenon have been observed through the high-speed camera. Quench front velocity is higher in the case of nanofluids than DI water due to the presence of nanoparticles in nanofluids. However, quench front shape also differs in the case of nanofluids due to the rupture of the boundary layer, which depends on agglomeration characteristics and the nanomicroporous layer formed on the solid surface of the heater. A better understanding of quench behavior, for a very low concentration of nanofluids, will make it a viable technology for emergency core cooling system (ECCS) for upcoming nuclear reactors in India.
