[0092] Example 1:
[0093] Take the up-flow anaerobic fermentation biological hydrogen production reactor with an effective volume of 3.35 liters as an example to carry out the process of optimizing the design of the hydraulic flow field. The specific operations are as follows:
[0094] (1) Pre-processing: geometric modeling and meshing
[0095] According to the actual geometric dimensions of the upflow anaerobic fermentation biological hydrogen production reactor (such as figure 2 As shown in the schematic diagram), use ANSYS GAMBIT 2.4.6 to perform geometric modeling and meshing of the reactor. During the modeling process, the thickness of the three-phase separation baffle and overflow baffle of the reactor is ignored, and it is approximated as a thin surface. structure.
[0096] Use such as image 3 with Figure 4 The shown unstructured tetrahedral grid generation method, and uses local grid densification to rearrange the grid points near the wall in the two calculation domains of...
