- class Air(*args, **kwargs)¶
Creates Phase object with preset models and values for air.
network (OpenPNM Network object) – The network to which this phase object will be attached.
project (OpenPNM Project object, optional) – The Project with which this phase should be associted. If a
networkis given then this is ignored and the Network’s project is used. If a
networkis not given then this is mandatory.
name (string, optional) – The name of the phase. This is useful to keep track of the objects throughout the simulation. The name must be unique to the project. If no name is given, one is generated.
>>> import openpnm as op >>> pn = op.network.Cubic(shape=[5, 5, 5]) >>> air = op.phases.Air(network=pn)
The table below shows all of the pore-scale models that are included with this class to calculate the physical properties of this fluid as functions of the relevant state variables.
This object is initialized at standard conditions of 298 K and 101325 Pa. If these conditions are changed, the dependent properties can be recalculated by calling
All of these parameters can be adjusted manually by editing the entries in the ModelsDict stored in the
modelsattribute of the object.
For a full listing of models and their parameters use
objis the handle to the object.
In addition to these models, this class also has a number of constant values assigned to it which can be found by running
The pore scale models for this class are taken from:
