An experimental investigation has been conducted on CHTE quench probes and IVF quench probes to determine the influence of flow rate, spray distance and concentration of AQ251 polymer quenchant on the cooling rate and heat transfer coefficient during spray quenching. Time-temperature data has been collected for each spraying condition using the CHTE spray quenching system. Heat transfer coefficients as a function of temperature have been estimated and compared by using lumped thermal capacity model and an inverse heat conduction model. The results revealed that the maximum cooling rate increases with increasing in the flow rate in varying concentration of polymer quenchant in both probes. It was also found that the cooling rate decreases with the increase of the concentration of polymer quenchant.
