**5.3 Initial and boundary conditions**

The freestream conditions for each trajectory point are tabulated in **Table 5**, which are used as initial conditions. The freestream flow values are used to initialize the whole flowfield.

The boundary conditions are as follows: a no-slip condition and isothermal wall is considered as a solid wall boundary condition. At the inflow, all the flow variables are taken at the freestream values as tabulated in **Table 5**. A symmetry condition is imposed on the centre line upstream and downstream of the reentry vehicle. All variables are extrapolated at the outer computational boundary.
