Approximations for the kinetic energy fraction \(K\)
@author: chloeg
Functions
- pttools.bubble.ke_frac_approx.calc_ke_frac(xi_w, alpha_n)
- Parameters:
xi_w (float)
alpha_n (float)
- pttools.bubble.ke_frac_approx.delta_k(alpha_n)
- pttools.bubble.ke_frac_approx.k_a(xi_w, alpha_n)
Small wall speeds xi_w << cs
- pttools.bubble.ke_frac_approx.k_b(alpha_n)
transition from subsonic to supersonic deflagrations xi_w = cs
- pttools.bubble.ke_frac_approx.k_c(alpha_n)
For Jouget detonations xi_w = xi_j
- pttools.bubble.ke_frac_approx.k_d(alpha_n)
- \[\kappa \approx \frac{\alpha_n}{0.73 + 0.083 \sqrt{\alpha_n} + \alpha_n}\]Hindmarsh et al., 2021 eq. 7.44 \(\xi_w\) => 1 v. large wall speed
