Sunil Mehendale (MMET) co-authored the article, “The influence of Header Design on Two-Phase Flow Distribution in Plate-Fin Heat Exchangers”, which has been accepted for publication in the ASME’s (American Society of Mechanical Engineers) Journal of Thermal Science and Engineering Applications.

This paper experimentally demonstrates that improved heat exchanger header designs through the use of carefully designed perforated plates placed prior to the entry of fluid into the heat exchanger can significantly aid in distributing the two-phase flow more evenly. Thereby, any degradation in the thermal-hydraulic performance of the equipment stemming from flow maldistribution can be effectively minimized.


Sunil Mehendale Comments on Geothermal Systems

A modern remix of old technologies that cuts home energy bills has the potential to utterly transform homes in the future, and the system was created in East Tennessee’s own Oak Ridge National Lab.

Scientists have developed prototype geothermal “batteries” that, unlike conventional batteries, actually tap and store the heat energy of the Earth to provide heating, cooling and hot water.

Phase change materials have been in use for at least a decade in diverse applications, from medical care to home climate control.

“None of these technologies themselves are new,” said Sunil Mehendale, associate professor of mechanical engineering at Michigan Tech. “But combining all these technologies together in one structure, that’s what brings the novelty.”

“I would really like to see how a full-scale device stacks up against current technology,” Mehendale added.
