Abstract

Boiling is the process through which a liquid is brought to a temperature at which it forms bubbles at solid-liquid interface and converts into vapour. The present work focuses on developing a system that involves less energy consumption for boiling of water. A thorough study of boiling process was made. The science behind the boiling curve of water is critically analysed. The four stages of boiling curve of water are studied, and a new theory called bubble disturbance theory is proposed. The transition region of the boiling curve shows decrease in heat flux pertained to poor heat conduction through bubbles formed at interface. A novel idea of disturbance of bubble at this stage to increase heat transfer rate was predicted. Experiments were conducted to observe the boiling of water with and without bubble disturbance. Results have shown that the proposed system with bubble disturbance will save energy up to 20%.
