FlowConfig flow configuration external classes

FlowConfig are the external classes used to describe flow configurations in exchangers and specify correlations to be used to calculate pressure dropsand Nüsselt heat exchange coefficients.

Regular pressure drop is calculated in the FlowConfig parent class by the calcDP() method. For polyphasic flows, the relay is passed to the calcDPdiff() method.

The calculation of singular pressure losses is done in the TechnoExch class.

The calculation of the Nüsselt number is specific to each FlowConfig.

A detailed presentation of the correlations used is given in this page.
