Study of pool boiling of mixtures to understand the effect of various factors on heat transfer.
What is it about?
Nucleate pool boiling is a simple phenomenon of boiling through a substrate (a copper plate in this case). The fluid of study in this paper is binary fluids which is basically a mixture of two fluids (one of them generally being water). These fluids undergoes the boiling process under varying parameters like concentration of liquids, type of liquid used, pressure, temperature, texture and material of the surface etc. This is done to enhance the heat transfer rate and heat flux between the substrate or plate and the fluid. The whole boiling process is observed using a high speed camera. The observations are recorded and analyzed and results are obtained. In this paper, we have compared various investigations and compared them. This is done to increase the efficiency of the various applications (hydrogen extraction, refrigeration, etc) of this process.
Why is it important?
The comparison between the various parameters of pool boiling has helped us to determine the best efficiency points. We were also able to determine the burnout regions for safety point of view. The increase in efficiency helps us to save a lot of time and money.
