}

Ablation model for surface recession under extreme heat flux.

Models the recession of a material surface when the surface temperature exceeds the ablation (sublimation or vaporization) threshold. The recession rate is governed by the Arrhenius-like expression.

Fields

t_ablation: f64

Ablation threshold temperature T_ab [K].

heat_of_ablation: f64

Heat of ablation (enthalpy of vaporization) L_ab [J/kg].

density: f64

Material density [kg/m³].

arrhenius_a: f64

Pre-exponential factor A [m/s].

activation_temp: f64

Activation temperature T_act = Ea/(R) [K].

Implementations

impl AblationModel

pub fn new( t_ablation: f64, heat_of_ablation: f64, density: f64, arrhenius_a: f64, activation_temp: f64, ) -> Self

Create a new ablation model.

pub fn recession_rate(&self, temp: f64) -> f64

Surface recession rate [m/s] at temperature T.

r = A * exp(-T_act / T) for T > T_ab, else 0

pub fn mass_loss_rate(&self, temp: f64) -> f64

Mass loss rate [kg/(m²·s)] = density * recession_rate.

pub fn ablative_heat_flux(&self, temp: f64) -> f64

Blowing heat flux [W/m²] absorbed by ablation = L_ab * mdot.

pub fn net_heat_flux(&self, applied_flux: f64, temp: f64) -> f64

Net surface heat flux after ablative cooling [W/m²].

q_net = q_applied - q_ablation
