热力学模型参数关联时，BIP 设定。help 文档You can load BIP data into your user database via the neutral file.The format of each BIP line is:
BIP type sec-ID BIP-A,
The BIP type must be one of the following:
NRTL
PR (Peng-Robinson)
SRK (Soave-Redlich-Kwong)
UNIQUAC
WILSON
BWRS
ESD
SAFT
Valid names are listed in the BIPNAMES.SF file in the system directory.
The BIP sec-ID is the secondary ID for this BIP data. Associated with each set of BIP values are, of course, two components; the primary component and the secondary component. The BIP keyword must be included somewhere between a pair of STRC and ENDC keywords. The STRC and ENDC keywords define a group of lines pertaining to the same component and it is assumed that this component is the primary component. The BIP sec-ID is the secondary ID associated with this BIP data and is the CHEMCAD ID number for the secondary component.You can specify any secondary ID so long as it is numerically less than the primary ID. For example, the following BIP line specifies values for WILSON BIPs between a user-added component and water (CHEMCAD ID for water is 62).
BIP WILSON 62 -52.605 620.63
If the current group of lines in your neutral file pertains to component 8001 and you include the following line in this group, it would be discarded because the secondary ID is greater than the primary ID:
BIP WILSON 8005 -52.605 620.63
The order in which you specify the BIP parameters is important. You must specify at least one BIP parameter. The maximum number of parameters depends on which BIP type you are specifying.
The BIPNAMES.SF file in the system directory includes the maximum number of parameters that can be specified for each BIP type. The order in which you specify BIP parameters is also important. The following list indicates the correct ordering for each BIP type:
BIP NRTL secID Bij, Bji, alphaIJ, Aij, Aji
BIP PR secID Bij
BIP SRK secID Bij
BIP UNIQUAC secID Aij, Aji, Uij, Uji
BIP WILSON secID Aij, Aji
BIP BWRS secID Kij
BIP ESD secID Kij, KTij, KaLin, dHLin, KaBin, dHBin
BIP SAFT secID Kij, KTij, KaLin, dHLin, KaBin, dHBin
