.... Originality/value This study presents a novel computational investigation of FSI effects on unsteady flow and heat transfer dynamics in wavy-walled cavities, addressing the gap in prior rigid-boundary assumptions by incorporating dynamic wall deformation. By coupling advanced numerical modeling of transient...

... pattern. Corresponding isoconcentrations of the fluid phase (last row) show more uniform distribution over the active walls and wide variations in the magnitudes about the cold walls. In fact, an entire wavy wall shows the presence of higher magnitudes of isoconcentrations, which is due to the waviness...
