| In this investigation, the performance of coolant in various operating conditions was examined through an energy analysis of experimental data. A novel method was introduced for presenting pool boiling test results, facilitating coolant performance assessment across distinct operational scenarios and enabling comparative energy analyses between transient and steady-state boiling. Leveraging principles of thermal science, distinct correlations were formulated to elucidate pool boiling phenomena in transient mode. analysis was based on experimental results from transient pool boiling tests conducted over predefined time intervals. analysis indicates a direct correlation between the heater's energy output and test duration. Notably, in a steady state, the energy rate produced as a result of Joule heating effects reached its maximum value, which is reflective of the extended duration of this state relative to transient state tests. Specifically, energy yield from the wire heater increased by 75% when the test duration was extended from 1s to 5s. Furthermore, extending duration to 10 s increased energy outputs by 62% and 186% compared to 5s and 1s durations, respectively. Performance decreases as a vapor film forms temporarily, before increasing and becoming nearly constant during film boiling. | ||
