| description | This work numerically investigated the strength of vortices behind a flexible vortex generator (FVG) by calculating the circulation using Fluid-Structural Interaction (FSI) simulation of RANS (SST) k-ω model. The total circulation showed the vortices formed by the FVG was more significant than those originated by the rigid vortex generator (RVG). From the analyses, the case with more significant structural velocity results in a larger shear or circulation. The structural velocity computation proves an excellent consistency with the model predicted values. This has suggested the reliability of the proposed model. Therefore, the performance of FVG in turbulence augmentation has been identified, suggesting enhanced turbulent transport for the greater heat transfer process. Next, the numerical model was extended to examine the heat transfer performance of the FVG. In general, the findings show that the employment of the FVG has a significant positive impact on the heat transfer process in the heat exchanger. |
