Title: Parameters Affecting Critical Heat Flux Of Nanofluids: Heater Size, Pressure Orientation And Anti-freeze Addition
Author: Kashinath, Madhav Rao
Abstract: This research aims at investigating the effect , heater size , pressure , heater orientation and effect of anti -freeze addition on critical heat flux of nanofluids which have shown large potentials as coolants for high power generating uses . Nanofluids have shown about ~180 - 200 % enhancement in the critical heat flux values . The effect of heater size employing three different sized heaters yielded about ~180 % enhancement over pure water . The effect of pressure on critical heat flux investigated by testing nanofluids at three pressures showed ~240 % increase in critical heat flux . Surface orientation effect on critical heat flux carried out for a 2 × 2 cm heater at five orientations revealed about ~120 % enhancement at 150° . Two commercially used antifreezes , ethylene glycol and propylene glycol were used to study the effect of anti -freeze addition to nanofluids . Alumina -water nanofluid of 0 .025 g /L concentration mixed with the antifreezes at five compositions by volume showed a maximum enhancement of about ~120 % for ethylene glycol and ~70 % for propylene glycol .
