sunpeek.components.fluids.WPDFluidDefinition

class sunpeek.components.fluids.WPDFluidDefinition(name, density_model, heat_capacity_model, manufacturer=None, description=None)

Bases: FluidDefinition

Definitions of WPD fluids, for reuse by WPDFluid subclasses

Notes

• To add to the database:

``` import onnx dens = onnx.load(‘E:/HarvestIT/tests/resources/fluids/FHW, Pekasolar/Pekasolar, pdf export, density.onnx’) hc = onnx.load(‘E:/HarvestIT/tests/resources/fluids/FHW, Pekasolar/Pekasolar, pdf export, heat capacity.onnx’) dens_m = fluids.wpd.ModelFactory(unit, onnx_model=dens) hc_m = fluids.wpd.ModelFactory(unit, onnx_model=hc) definition= WPDFluidDefinition(unique_name, dens_m, hc_m, manufacturer=, datasheet_info) with Session(module_engine) as session:

session.add(definition) session.commit()

```

Methods

__init__(name, density_model, ...[, ...])	A simple constructor that allows initialization from kwargs.
add_component_attr(name[, unit, minimum, ...])
all_subclasses([c])
define_component_attrs()
from_fluid_info(fluid_info)
get_component_attribute(name)
get_default_unit(name)	Return default unit of a class attribute defined as ComponentParam.
get_definition(fluid_string, session)	Tries to find a match for fluid_string among fluids definitions.
register_callback(callback_type, func)
set_component_attribute(name, value, array_type)

classmethod get_default_unit(name)

Return default unit of a class attribute defined as ComponentParam.

Return type:

str

classmethod get_definition(fluid_string, session)

Tries to find a match for fluid_string among fluids definitions. Compares lower case and neglecting whitespaces. Checks against name and description.

Parameters:

• fluid_string (str) – User-supplied string that must uniquely define a fluid within the CoolProp incompressible fluids, or predefined wpd_fluids. See `CoolProp Incompressibles`_.

• session (sqlalchemy.orm.session.Session) – An active database session object

Return type:

A CoolpropFluidDefinition or WPDFluidDefinition object if a unique match for `fluid string is found in the fluid_definitions table`

Raises:

ValueError – If no or more than one fluid is found.
