Abstract: To obtain the velocity of flow field for cell attached
uniformly and for nutrients supplied successfully, effect of the various
angles between main channel and branching channels and of the location
of the branching channels along the main channel on velocity of flow in
branching channels is studied by numerical analysis. And a new ductwork
design is presented based on microstructure of natural bone and
conversation of energy and flux. The 3D viscous computational fluid
dynamics (CFD) analysis is carried out on it. The 3D flow simulation
results are compared with that of ordinary structure. The conclusion
shows that such a 3D flow channel arrangement produces higher velocity
and more uniform distribution of velocity in branching channels. That is
to say, cell attachment is more uniform and making the number of
branching channels increased is possible.
