Numerical Simulations of Heat Transfer and Flow Structure for Tubular Reactors

摘要

Numerical simulation techniques were applied to investigate heat transfer-and flow structure in tubular reactors. The tube bundle zone was modeled as an anisotropic porous media and flow resistance of the zone was evaluated using published experimental data. Leakage of heat transfer salt through the gaps between tubes and baffle plates was considered, as well as leakage through the gaps between shell and baffles. Distributions of the pressure loss were compared with experimental data from Argonne National Laboratory (ANL) for validation of the simulation models. Finally, the method was applied to examine temperature distribution and flow structure for scale up design of a tubular reactor.
