Abstract: The maximum surface heat flux is determined during jet impingement quenching of hot vertical stainless steel surface of 800 ± 10 °C initial temperature. Water jet through a sharp edge nozzle of 24 ± 1 °C temperature is injected on a vertical test surface of 0.25 mm thickness. The investigation is made up for stagnation point to 24 mm downstream location above and below of the stagnation point. Water flow is regulated to maintain the jet Reynolds number in the range of 5000–24,000. It has been observed that maximum surface heat flux is highest for the stagnation point and reduces monotonically for the downstream spatial locations. The decrease in maximum surface heat flux is higher for the locations above the stagnation point as compared to the locations below the stagnation point. However, for the entire measured spatial locations the maximum surface heat flux increases with the rise in jet diameter and coolant flow rate. The proposed correlation for the maximum surface heat flux predicts experimental data within an error band of ±15%. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
