The present study demonstrates a numerical approach to fluid-structure interaction and associated heat transfer enhancement in a thermal system under the action of a dynamic flexible flow modulator. The thermal system under consideration consists of a vented domain undergoing isoflux heating on the right sidewall, where one end of the modulator is attached at the mid-position in cantilever fashion and undergoes external periodic oscillation at its free end. Galerkin finite element method resolved in Arbitrary Lagrangian-Eulerian approach is adopted to solve the present problem. Effects of amplitude and period of oscillation, as well as the flexibility of the modulator on flow and thermal fields, heat transfer performance, and induced thermo-fluid system characteristics, have been studied. Results obtained in this study reveal the significant impact of external oscillation and flexibility of flow modulator on the degree of …
