  • a high level programming language implementation of topology optimization applied to steady state navier stokes flow
    International Journal for Numerical Methods in Engineering, 2006
    Co-Authors: Laurits Hojgaard Olesen, Fridolin Okkels, Henrik Bruus
    Abstract:

    We present a versatile high-level programming-language implementation of non-linear topology optimization. Our implementation is based on the Commercial Software Package FEMLAB, and it allows a wide range of optimization objectives to be dealt with easily. We exemplify our method by studies of steady-state Navier–Stokes flow problems, thus extending the work by Borrvall and Petersson on topology optimization of fluids in Stokes flow (Int. J. Num. Meth. Fluids 2003; 41:77–107). We analyse the physical aspects of the solutions and how they are affected by different parameters of the optimization algorithm. A complete example of our implementation is included as FEMLAB code in an appendix. Copyright © 2005 John Wiley & Sons, Ltd.

  • effect of impeller clearance on flow structure and mixing in bioreactor with two stage impellers
    Engineering in Life Sciences, 2001
    Co-Authors: Long An Shang, Do Hyun Kim, Ho Nam Chang
    Abstract:

    The effect of impeller clearance on flow structure and mixing time was simulated using a Commercial Software Package CFX 4.3 and was measured experimentally. The mixing time calculated by simulation exhibited good agreement with the experimental data. The trend of forming independent flow compartments by each impeller became stronger as the clearance between two impellers increased. The homogeneity in the bioreactor was affected mainly by flow exchange between the compartments by each impeller. The most efficient mixing occurred when the impeller clearance was in the range of 0.2-0.4 vessel diameter.
