heat transfer coefficient and pressure drop for working fluid, changes automatically to 1phase if necessary.

Parameters:

  • fluid (TYPE) – DESCRIPTION.

  • fluidstate (TYPE) – DESCRIPTION.

  • mdot (TYPE) – DESCRIPTION. mass flow rate [kg/s]

  • method (TYPE) – DESCRIPTION. Nusselt correlation as in ht database or constant

  • l (TYPE) –

    DESCRIPTION. length of tube (only used for flow field as reference

    length) [m]

  • d_big (TYPE) – DESCRIPTION. diameter [m]

  • U_i (TYPE, optional) – DESCRIPTION. The default is 0. please set, if constant U shall be used

Returns:

  • alpha_KM (TYPE) – DESCRIPTION. heat transfer coefficient [W/(m^2*K)]

  • dp_wf (TYPE) – DESCRIPTION. differential pressure loss [Pa/m]
