### CombCharFixed02

icon:

inject flue gas and heat into inlet fluid.

#### Scope/Calculation function

- Calculation of the change in state quantities and fraction of fluid composition through combustion chamber.
- Chemical reaction of combustion is NOT included.
- Fuel flow rate is read from flow into "port_fuel", NOT directly input to this comonent

#### Short description of physical model/calculation method

- Fluid of burned fuel and inlet fluid are mixed.
- The heat generated by combustion is injected into fluid flow after mixing of fluid.
- The combustion efficiency, what fraction of fuel is converted to heat (about 0.99 in most of case) can be input via parameter or real input connector.

#### Limitations/Assumptions of model

- Chemical reaction in NOT included in this component. Therefore, the composition of flue gas must be known at "port_fuel".
- Friction Loss and Rayleigh loss are NOT included.

#### Interface

#### Parameters

Read the descriptions on parameter window in model for details of each parameter. This section only covers parameters which requires descriptions by figures/drawings.

#### Usage

- Redeclear the package of medium.
- Fill following connectors:

- fluid ports, _1, _2, and _fuel.

- Decide how to provide Lower Heating Value of Fuel

- Provide by parameter.

1. Leave "use_u_LHV_fuel" unchecked (false).
2. Set value of "LHV_fuel_paramInput".

- Provide by real input connector.

1. Set "use_u_LHV_fuel" checked(true).
2. Fill the connector "u_LHV_fuel."

- Decide how to provide combustion efficiency.

- Provide by parameter.

1. Leave "use_u_effComb" unchecked (false).
2. Set value of "effComb_paramInput".

- Provide by real input connector.

1. Set "use_u_effComb" checked(true).
2. Fill the connector "u_effComb."

Thats all.
