AB In the absence of disadvantages of various cooling methodologies reported in the literature, in the
current work, enhancement at high temperature by using low mass flux spray recommended for cooling of thin strip is achieved. By decreasing the droplet renewal rate and augmenting the residence time, the aforesaid has been achieved. In the current work, from the attainment of these conditions in the cooling process, the spray cooling was made intermittent. The result reveals that heat extraction
rate enhances with increasing the mass flux from 0.25 × 10-6 to 9.25 × 10-6 kg/m2s and further increment in mass flux decreases the heat transfer rate. In addition, the obtained critical heat flux (CHF) is higher than the CHF achieved by changing the nozzle orientation and the achieved TCHF
is lower in the case of a multispray low mass flux nozzle. Further, comparative study clearly reveals significant reduction of coolant consumption rate and operating pressure in comparison with the information reported in the literature. However, the CHF and heat transfer coefficient are comparable but lower.
