The volume of a fluid model was used to simulate the process. The effect of nozzle angle equal to 15, 30, and 45 degrees, nozzle jet velocities of about 10 and 8 m/s, tinplated velocities of 244, 200, and 160 m/min, and cooling fluid temperature of 30, 40, and 55 °C on the tinplate temperature field was investigated. Results show that the tinplate temperature field is relatively uniform at a 45° nozzle angle. In addition, a more uniform temperature field was obtained by increasing the nozzle jet velocity from 8 m/s to 10 m/s and decreasing the tinplate velocity from 244 m/min down to 160 m/min. https://jhmtr.semnan.ac.ir/article_9763_0ffd15f002b98f6bd62346b947b8d15a.pdf
