In this study, the incorporation of a flexible baffle structure at base microelectronic channel is examined to determine its impact on thermal and fluid dynamics. The investigation covers two configurations: case 1, where heat source situated top section microchannel, 2, with placed bottom. To cool electronic component, nanofluid consisting water aluminum oxide (Al2O3) nanoparticles, in concentrations varying from 0% 6%, injected into exhibiting periodic velocity profile inlet. governing equations for system are resolved using finite element method numerical simulation. results show that shape curvature significantly affect dissipation efficacy. particular, setup located bottom, adjacent baffle, demonstrates most advantageous cooling performance. data also positive relationship between nanoparticle volume fraction enhanced transfer, particularly when near bottom shapes S = −20 −10, implying superior convective transfer. findings indicate optimal outcomes achieved there reduction pressure drop resistance.

International Journal of Thermofluids, Journal Year: 2024, Volume and Issue: 22, P. 100687 - 100687

Published: May 1, 2024

The present study aims to numerically explore Fluid-Structure Interaction (FSI) induced mixed convection characteristics in a square cavity filled with non-Newtonian power-law fluid. side walls of the under consideration are subjected constant low temperature having motion opposite directions while insulated top wall and bottom hot kept stationary. A flexible fin is mounted on that essentially serves as passive flow modulator. To solve transient flow, thermal, stress fields, FSI problem presented an arbitrary Lagrangian-Eulerian framework employing Galerkin finite element method. Different fluids represented by index (n) varied within range, 0.6 ≤ n 1.4. Besides, dynamic well condition analyzed variation Reynolds number (100 Re 300) Richardson (0.1 Ri 10.0) respectively. System have been evaluated terms streamline isotherm contours, spatial time-averaged Nusselt Normalized regard "No Fin" case. outcome reveals efficacy for given system depends both (Re) regime (Ri). presence has found positive impact heat transfer performance shear-thinning shear-thickening higher values Ri. However, lower Re, inclusion adversely affect fluids. Moreover, thermal field exhibits periodic oscillation properties at = 10, which can be attributed fin. This phenomenon further elucidated through Power Spectrum Analysis. Results obtained might provide valuable insights into FSI-induced versatile industrial applications such solar collectors strategically positioned modulators.
