**************************** **Flory-Huggins parameters** **************************** :: Flory-Huggins parameters = CONSTANT ----------------------- **Description / Usage** ----------------------- This card specifies the Flory-Huggins binary interaction parameters. It is assumed that the binary parameters are symmetric; i.e., .. figure:: /figures/462_goma_physics.png :align: center :width: 90% Therefore, one set of i-j coefficients is sufficient to describe the binary interaction coefficients. +--------------------------+-------------------------------------------------------------------------------------+ |**CONSTANT** |Model for constant Flory-Huggins parameters. | | | | | | * - first species number. | | | * - second species number. | | | * - Flory-Huggins binary interaction coefficient. | +--------------------------+-------------------------------------------------------------------------------------+ ------------ **Examples** ------------ Following is an example set of cards for a three-species mixture: :: Flory-Huggins parameters = CONSTANT 0 1 0.3 Flory-Huggins parameters = CONSTANT 0 2 0.3 Flory-Huggins parameters = CONSTANT 1 2 0.3 This example shows that two species are solved in the *Goma* problem explicitly: species 0 and species 1. ------------------------- **Technical Discussion** ------------------------- No discussion; see Sun (1998). -------------- **References** -------------- GTM-007.1: New Multicomponent Vapor-Liquid Equilibrium Capabilities in GOMA, December 10, 1998, A.
