摘要：
We are developing a superconducting magnet system for growing high-quality protein crystals from solutions in a reduced gravity environment by magnetic force. In order to estimate a suitable reduced gravity environment by magnetic force for protein crystal growth, we propose a flow simulation model that elucidates the motion of multicomponent solutions under magnetic force. The simulation model is based on the Navier-Stokes equation and is applied to analyzing effects of different factors on the fluid flow in protein solutions. Numerical calculation results indicate that magnetic force strongly influences the protein solution flow through magnetic susceptibility distribution in fluid. (C) 2012 American Institute of Physics.
