modelConvectiveBoundaryLayer
Convective boundary layer with variable exponent (TF75 C2K)
Extends from BaseClasses.HeatTransfer.Interfaces.Element1D (Partial heat transfer element with two HeatPort connectors that does not store energy).
Information
Hypothesis and equations
This model allows to define a convective heat exchange coefficient between a fluid and a wall, in the form of :
Q_flow = h.S.(deltaT)alpha
