Experimental and Computational Fluid Dynamics Studies on Straight and U-Bend Double Tube Heat Exchangers with Active and Passive Enhancement Methods

Rafal Andrzejczyk et al.

Summary: The authors aimed to increase heat transfer efficiency by utilizing wire coil inserts and air blowing in double tube heat exchangers. Experimental investigations and computational fluid dynamics techniques were employed to study the impact of these methods on heat transfer, pressure drops, and overall efficiency. Results showed an improvement in heat transfer efficiency, especially when using the NTU-epsilon method for comparison.
