Fixed temperature

Table of Contents

This constraint will fix the temperature in the energy equation in the mesh region specified, regardless of incoming flow temperature or local flow behaviour.

Properties

Downstream of the constraint the temperature field will continue to develop normally. Please note this will only affect the temperature field. Other thermodynamic fields, e.g. density, may still show sensitivity to the local pressure (if applicable). Note that this constraint will cause a non-conservation of energy. No information will be added to the log file other than the identification of the constraint at the start of the simulation.

Usage

fixedTemperature
{
    type            fixedTemperatureConstraint;
    active          yes;

    selectionMode   cellZone;
    cellZone        porosity;

    mode            uniform;      // uniform or lookup

    // For uniform option
    temperature     constant 500; // fixed temperature with time [K]

    // For lookup option
    // T            <Tname>;      // optional temperature field name
}
