However, the source function is used to provide an adequate abstraction of the physical phenomena considered. Rules 1: A source has one output… read more »

Flow functions

In MFM functions are defined in relation to the processing of flows of mass and energy. MFM is based on a set of six generic flow functions representing different primitive operations performed on either mass or energy flow. These six functions are shown in the figure below and include: source, transport, storage, sink, balance and… read more »
