4. CFD applications in scroll machine design
Recent application of CFD techniques in designing of positive
displacement machines is playing a vital role. CFD simulation of the
positive displacement machines was carried out earlier in London
City University Compressor Centre [93], and also specifically
applied for screw compressors [94,95]. However, the CFD simulation
for the scroll machine is still in early stage because of the
complex geometry and unique motion of orbiting scroll wrap.
In the past few years, some researchers have applied CFD
method to reveal the inner flowcharacteristics and thermodynamic
performances of the scroll machine in two dimensions and three
dimensions with different models and schemes, as shown in
Table 6.
