v0.2.2 - Rankine’s Realm (March, 6, 2020)#
New Features#
Allow initialisation for the primary variables from previous calculation. Until now, the user needed to save the network’s state and reload that state for his next simulation. This feature is enabled as default. If you want to disable this feature, you need to state
mynetwork.solve(..., init_previous=False)
(PR #156).Extrapolation for characteristic lines is available. In default state, the upper or lower value range limit is used when a characteristic line is evaluated outside of the available x-value range. The
extrapolate
parameter allows linear extrapolation, for an example see the corresponding sections in the online documentation: component characteristics, tespy characteristics (PR #159).Add a new component evaporator for geothermal organic rankine cycle. The component has inlets for geothermal steam brine. On the cold side, the orc working fluid is evaporated. Read more about this component in the API documentation:
tespy.components.customs.orc_evaporator
(PR #148).
Parameter renaming#
Testing#
Bug fixes#
Fix the bugged tests for compressor characteristic maps (
tespy.components.turbomachinery.compressor.char_map_func()
). The pressure ratio factor of the lowest speedline available in the default data ranges from about 0.2 to 0.5. Therefore the design pressure ratio should be higher than 5 (PR #156).
