      Particle simulation of crystal growth and settling under variable gravity 

      Gatsonis, N. A.; Ongewe, B.; Alexandrou, Andreas N.; Jr, A. Sacco (American Institute of Aeronautics and Astronautics Inc, AIAA, 1999)
      A model that describes crystal growth and motion is presented. The model is based on concept of the direct simulation Monte Carlo and molecular dynamics methods and includes spherical crystal particles, nutrients species ...

      A two-phase fluid model of crystal settling under variable gravity 

      Alexandrou, Andreas N.; Shi, H.; Gatsonis, N. A.; Jr, A. Sacco (American Institute of Aeronautics and Astronautics Inc, AIAA, 1999)
      A two-phase fluid model of crystal particle motion in a liquid is presented. The model includes a liquid and a solid phase as continua and forces due to pressure, viscous stresses, variable gravity and fluid drag. The model ...
