modelExtConvection
Convective heat exchange coefficient taking into account the wind
Extends from BaseClasses.HeatTransfer.Interfaces.Element1D (Partial heat transfer element with two HeatPort connectors that does not store energy).
Information
Hypothesis and equations
Generic correlation of the convective heat exchange coefficient depending on the wind speed :
hcv = a * vn + b
