The studies of flow phenomena, heat and mass transfer in microchannel reactors are
beneficial to estimate and evaluate the ability of microchannel reactors to be operated
for a given process reaction such as Fischer-Tropsch synthesis. The flow phenomena,
for example, the flow regimes and flow patterns in microchannel reactors for both
single phase and multiphase flow are affected by the configuration of the flow
channel. The reviews of the previous works about the analysis of related parameters
that affect the flow phenomena are shown in this report. In order to predict the
phenomena of Fischer-Tropsch synthesis in microchannel reactors, the 3-dimensional
computational fluid dynamic simulation with commercial software package
FLUENT was done to study the flow phenomena and heat transfer for gas phase
Fischer-Tropsch products flow in rectangular microchannel with hydraulic diameter
500 ¿m and length 15 cm. Numerical solution with slip boundary condition was used
in the simulation and the flowphenomena and heat transfer were determined.
