Boundary Conditions

in Radiating Bondi Flows I

For the outer boundry conditions \(r \rightarrow \infty\) \[ (\tilde{\rho},\mathcal{M}, s, \tilde{L}, \tilde{E}_\text{r}) \rightarrow (1, 0, s_\infty, \tilde{L}_\infty, 1) \]

With dimensionless density \( \tilde{\rho} = \frac{\rho(r)}{\rho_\infty}\), Mach number \(\mathcal{M} = \frac{v(r)}{c_s(r)}\), dimensionless entropy \( s = \frac{S}{c_\text{V}}\) and dimensionless radiation Energy density \(\tilde{E}_\text{r} = \frac{E_\text{r}}{a_\text{r}T_\infty^4}\).

in PLUTO/belt

Code-Anpassungen für konstante Zentralmasse

(Lothar)

  • M_centr (o.Ä.) als weiteren Parameter in user_defined_parameters.h definieren und die Anzahl USER_DEF_PARAMETERS entsprechend erhöhen
  • den Wert von M_centr in pluto.ini unter [Parameters] setzen (in Gramm)
  • body-force.c aus belt/src/Misc in den Run-Folder kopieren und in Zeile 64 die M_X1_BEG durch (g_inputParam[M_centr]/ReferenceMass) ersetzen
