Abstract
With the development of supercritical fluid technology, supercritical CO
2 has great applications in carbon
sequestration, soil remediation, recovery of petroleum gas, material extraction in industrial processes, and
product pure drug nanoparticles/nanocrystals. In these applications, the flow and heat transfer, phase
change of sCO
2 in porous media are involved. Combined with the previous research methods, we establish a
three-dimensional microchannel chip porous media model. Using the numerical simulation method, we
study the flow and heat transfer characteristics of sCO
2 in the microchannel chip porous media under
different working conditions. The temperature, pressure and density distribution are obtained under
different working conditions. We also investigate the influence of inlet conditions such as mass flow and
inlet temperature on pressure drop between inlet and outlet of porous media model and heat transfer
coefficient between CO
2 and heating wall of microchannel chip. The results show that the increase of mass
flow rate and inlet temperature will increase the pressure drop, while the increase of outlet pressure will
decrease the pressure drop. The increase of mass flow will enhance heat transfer, while when the inlet
temperature exceeds the critical temperature of CO
2, the increase of inlet temperature will inhibit heat
transfer. The variation of heat transfer coefficient in different regions of the numerical model is also
observed.
