What is it about?

The idea of thermodynamic irreversibility is central to the understanding of entropy. We shown for the first time that the entropy generation of the system increases at the two walls of the channel as well as the heat transfer irreversibility is dominant there, whereas the fluid friction irreversibility is dominant along the centerline of the channel.

Why is it important?

For any thermal system, as the entropy generation increases, the energy decreases. Thus, to enhance the efficiency of the system, the rate of entropy generation must be effectively controlled.


It was a great pleasure to write this article as it has a co-author who is working for long time in MHD Jeffery-Hamel flow in convergent-divergent channel. This article also lead to rare disease groups contacting me and ultimately to a greater involvement in rare disease research.
