Parameters

[in,out]

prm

ParameterHandler.

Post operation

Set default values of parameters, after parameters have been parsed.

Parameters

[in]	material	Material data.
[in]	use_volume_specific_thermal_capacity_for_phase_interpolation	Set to true if the volume-specific heat capacity is interpolated as a single quantity across the interfaces.

compute_linear_scaling_coeff() [1/2]

template<typename number >

dealii::VectorizedArray< number > MeltPoolDG::Evaporation::compute_linear_scaling_coeff ( const dealii::VectorizedArray< number > &  T, const number  T_ac, const number  T_v  )

inline

Compute a linear activation scaling coefficient.

The scaling coefficient is used to smoothly activate a quantity (e.g., recoil pressure or evaporative cooling) between an activation temperature and a boiling temperature. The coefficient is defined as

\[ s(T) = \begin{cases} 0, & T \le T_{\mathrm{ac}}, \\ \dfrac{T - T_{\mathrm{ac}}}{T_{\mathrm{v}} - T_{\mathrm{ac}}}, & T_{\mathrm{ac}} < T < T_{\mathrm{v}}, \\ 1, & T \ge T_{\mathrm{v}}. \end{cases} \]

where \(T_{\mathrm{ac}}\) is the activation temperature and \(T_{\mathrm{v}}\) is the boiling temperature.

Parameters

T	Temperature at which the scaling coefficient is evaluated.
T_ac	Activation temperature.
T_v	Boiling temperature.

Returns

The scaling coefficient in the range \([0,1]\).

compute_linear_scaling_coeff() [2/2]

template<typename number >

number MeltPoolDG::Evaporation::compute_linear_scaling_coeff ( const number  T, const number  T_ac, const number  T_v  )

inline

Same as above, just for the vectorized case.

compute_saturated_gas_pressure()

template<typename number , typename number_2 >

number_2 MeltPoolDG::Evaporation::compute_saturated_gas_pressure ( const number_2 &  T_sat, const number  boiling_temperature, const number  ambient_gas_pressure, const number  temperature_constant  )

inline

Calculate the saturated vapor pressure at a certain vapor temperature according to the Clausius-Clapeyron equation.

Parameters

T_sat	Saturated vapor temperature.
boiling_temperature	Boiling temperature at atmospheric pressure conditions.
ambient_gas_pressure	Ambient gas pressure.
temperature_constant	Temperature constant; It should be computed from latent_heat_of_evaporation * molar_mass / universal_gas_constant.

Returns

Saturated vapor pressure at the provided saturated vapor temperature T_sat.

Note

The template parameter

Template Parameters

number_2

allows a vectorized computation.
