Hx1DConst

Information

Model Hx1DConst represent the model of a counter-current heat exchanger in which one of the two fluid is a constant heat capacity fluid. It is based on the connection of different sub-components:

  • A Flow1Dim component representing the flow of the fluid in one side of the exchanger
  • A Flow1DConst component representing the flow of the fluid in the other side of the exchanger
  • A MetalWall component representing the thermal energy accumulation in the metal wall
  • A CountCurr component that enables the possibility of parallel or countercurrent flow

Modelling options

In the Initialization tab the following options are availabe:

  • steadystate_T_sf: if true, the derivative of temperature of the constant heat capacity fluid is set to zero during Initialization
  • steadystate_h_wf: if true, the derivative of enthalpy of the working fluid is set to zero during Initialization
  • steadystate_T_wall: if true, the derivative of temperature of the metal wall is set to zero during Initialization

Numerical options

The numerical options available for the HxRec1DConst are the one implemented in Cell1Dim and CellConst.
