Investigation of Heat Transfer in Concentric Tube Heat Exchanger

The book delves into heat transfer augmentation techniques, focusing on innovative triangular inserts that enhance turbulence in fluid flow, thereby increasing heat transfer rates. It includes a literature review on passive techniques and presents experimental findings on the performance of these inserts in both counter and parallel flow configurations. Results indicate that twisted triangular inserts can significantly boost the heat transfer coefficient while also increasing friction factors. Additionally, it notes the relationship between Reynolds number and the variations in heat transfer and friction factors.
