Özet

Ever-increasing consumption of limited energy sources forces researchers and engineers to produce more efficient energy systems in order to use energy sources effectively. Enhancing the heat transfer rate with an acceptable pressure drop is an important parameter to produce more compact heat exchangers which are used in air-conditioning systems, chemical reactors, thermal power plants and others. Nowadays many engineering techniques such as surface modifications, swirl flow creators, flow conditioners, additives, etc. are implemented to enhance the heat transfer performance of energy systems. Researchers are still interested in the implementation of these techniques to improve the performance of energy systems further although the current literature has many experimental and numerical research data. Even though the corrugated channel is a passive technique to augment heat transfer, researchers have been insisting on trying to get further improvement by implementing one or more passive/active techniques to corrugated channels. The objective of the present work is to gather available research data which particularly focus on the flow characteristics and heat transfer rates through the corrugated channels. The design parameters, practical limitations and conclusions of energy systems, obtained previously are presented in tabular forms and the necessary discussion is also provided.
