Understanding how heat propagates from one material to another is crucial for designing efficient cooling systems and heat-resistant buildings. Researchers from the University of the Philippines Diliman (UPD) have formulated a new theory. This theory improves the modeling of heat transfer through rough surfaces.
The theory was developed by Jake Avila of the UPD College of Science Institute of Mathematics (UPD-CS IM). It uses a method called homogenization. This method combines the tiny details of a material with its larger, more uniform properties. This allows for a more accurate modeling of heat propagation, especially in uneven surfaces.
Avila’s theory has applications beyond heat transfer. It can describe other physical phenomena like sound wave propagation and turbulence flow. The researchers are now working on developing a more general version of the theory for wider applications.
