摘要

The present work is focused on energy conservation for the pool boiling applications with and without eco-friendly red areca nut as an additive in the deionized water. The aqueous red areca nut solutions having concentration 100-600 ppm is considered to quantify the effect on pool boiling heat transfer and bubble phenomenon. It is observed that as the concentration increases and goes up to 500 ppm, it shows the increase in heat transfer rate with the smaller wall superheat. The critical heat flux observed at 908.24 kW/m~2 with a minimum wall superheat at 63.5°C and the further increase in concentration, the wall superheat is also increased which shows the loss of heat energy in pool boiling experiments. The similar result is obtained for bubble phenomenon that an increase in concentration has a decrease in bubble diameter and increase in velocity compared to deionized water. It is also observed that the relative heat transfer coefficient with additive solutions shows 80% enhancement in the performance of heat transfer as compared to deionized water only.
