pipeline studio4.0求問

lalaland

今天裝了軟件，跟著教程學的時候發現simulation→option→fluid→viscosity里面沒有calculate了，取而代之是一個下拉菜單里面有個LEG、LEG-3、LEG-4，這個LEG是什么意思？

誰會��？說一下唄

LEG 就是用來計算粘度的經驗公式。在幫助里邊有。如果不知道該選那個就選LEG

To have the simulator calculate the viscosity of the gas using the Lee-Gonzalez-Eakin (LGE) correlation, select LGE, LGE-3 or LGE-4 as outlined below.

If the user selects LGE then the standard LGE fluid viscosity correlation (i.e. the LGE viscosity correlation using the standard set of parameters, defined in file LGECoeff.pvt in PipelineStudio Gas) will be used to calculate the fluid viscosity throughout the simulation.

If the user selects LGE-3 then the LGE-3 fluid viscosity correlation (i.e. the LGE viscosity correlation using the LGE-3 set of parameters, defined in file LGECoeff.pvt in PipelineStudio Gas) will be used to calculate the fluid viscosity throughout the simulation.

If the user selects LGE-4 then the LGE-4 fluid viscosity correlation (i.e. the LGE viscosity correlation using the LGE-4 set of parameters, defined in file LGECoeff.pvt in PipelineStudio Gas) will be used to calculate the fluid viscosity throughout the simulation.

Note: LGECoeff.pvt is stored in the TGNET folder under the installation directory in PipelineStudio Gas. The file is a fixed format plain text file allowing users to modify parameters if they so wish. User modified parameters will not be supported by ESI
