CFD Simulation of Heat Transfer in Taylor Flow Regime Passed Through a Single Channel of Monolithic Reactor

In this contribution, heat transfer of the Taylor flow regime in one tube of monolithic reactor has been studied by CFD simulation. The regime has been assumed to be periodic and axis symmetric. The volume of fluid based (VOF) interface tracking method was used for hydrodynamics simulation. In this case the bubble is stationary and liquid flows over it. In order to investigate the effect of Taylor bubble on heat transfer enhancement, heat transfer phenomenon has also been simulated for liquid only flow. Afterwards the effects of capillary number and gas volume fraction variations have been studied. The results show that in every capillary number the heat transfer has been increased by volume fraction enhancement. The results also show that the average Nusselt number has been increased by capillary number enhancement till 0.2. The average Nusselt number has been smoothly decreased by further capillary number promotion.
