Abstract
A numerical simulation is performed to study the influence on the heat transfer rate of the heated wall in the channel with an oscillating cylinder. An arbitrary Lagrangian-Eulerian kinematic description method is adopted to describe the flow and thermal fields. A penalty consistent finite-element formulation is applied to solve the governing equations. The effects of Reynolds number, oscillating amplitude, oscillating frequency, eccentric ratio, and blockage on the heat transfer characteristics of the heated wall are examined. The results show that not only the region relating to heat transfer is enlarged substantially, but also that the heat transfer rate of this region is enhanced remarkably.
