Plate heat exchanger correlations

The model PartialPlateHeatExchangerCorrelation is the basic model for the calculation of heat transfer coefficients for plate heat exchangers. It provides some basic geometric definitions. It returns an enhanced HTC U based on geometry and alpha. Thus U can be used with the projected squared area of the device, which is also the way the discretised models work at the moment.

The geometry of the plate heat exchanger plates is defined by the parameters of this partial model. The most important ones can be found in the Geometry section of the parameter window:

• a_hat - Corrugation amplitude
• phi - Corrugation angle (phi_co on drawing)
• Lambda - Corrugation wavelength (l_co on drawing)
• B_p - Plate flow width (d_hx on drawing)

The more specific ones are defined by equations, which can be altered in the parameter window:

• X - Wave number
• Phi - Enhancement factor
• d_h - Characteristic length
• A_cro - Cross-sectional area

The default definitions are taken from Martin2010, but other correlations might use these parameters differently. Hence the possibility to modifiy the equations.
