Abstract
Abstract The flow characteristics pattern and heat performance improvement have been analysed by applying the computational method in 3D corrugated configuration tubes. Configuration were carried out with varying geometrical parameters, counting various ring corrugated angle over a tube at several Re range between 4000 and 12000. Computational outcomes in this investigation were validated with available experimental data. Outcomes noted that there was a significant alteration in the behavior of flow structure hence an important rise in pressure losses and enhancement in thermal performance due to using corrugated configurations when compared with the normal plane pipe. By utilizing the latter tube under varying parameters, it produces more turbulence flows, separation, mixing, and more distribution in the boundary flow layer, hence enhancing the thermal flow performance. Furthermore, pressure and Nu were augmented when corrugated configurations rise. Besides, these configuration parameters have a significant impact on the value of overall heat performance. Then the higher value was about larger than 1.65. Computational calculations can provide good results on fluid structure inside the pipe and heat transfer augmentation.
