A novel laboratory experiment for demonstrating boiling heat transfer

An undergraduate laboratory experiment for hands-on experiential learning of boiling heat transfer is described. The experiment allows the students to visualize and qualify different modes of boiling heat transfer. Experimental measurements are used for estimating the boiling heat transfer coefficient at varying heat flux and in the presence or absence of stirring. In addition, the results are compared with those obtained from theoretical calculations using correlations available in the literature. Overall, the experiment is well received by the students as it provides them with the opportunity of team work, leadership role, and the spirit of industrial experience. The experiment provides them with the ability to plan and execute a relatively complex but important heat transfer operation. The experiment additionally enhances student understanding of the boiling heat transfer topic covered in classroom lectures.
