Prescribed heat flow boundary condition

Thermal/HeatTransfer/Sources

Description

This model allows a specified amount of heat flow rate to be transferred into a thermal system. The amount of heat flow rate is given by the input signal Q_flow (left). If Q_flow is positive then the heat flows from this component to another component connected to the heat port (right).

If the parameter alpha is > 0 then the heat flow is multiplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given at reference temperature T_ref).

Parameters

    PrescribedHeatFlow_0

  • T_ref [K] : Reference temperature (T_ref): Scalar.
  • alpha [1/K] : Temperature coefficient of heat flow rate (alpha): Scalar.

Ports

  • Port 1 at left position: implicit input fixedport numbered 1.
  • Port 1 at right position: implicit output fixedport numbered 1.
