[TRNSYS-users] Type 534-Coiled Heat exchanger parameters

Dear TRNSYS users,

I am trying to use type 534-coiled from the TESS Storage Tank library, with a coiled heat exchanger. To specify the UA value of the heat exchanger some parameters are needed: Multiplier for natural convection (C), Exponent for natural convection (n), Geometry factor for natural convection (GF), and Geometry exponent for natural convection (m). Does somebody have more information about those parameters, for example a range of typical values for each parameter?

Kind regards,
