When +using a Riemann solver to transmit the boundary condition to the boundary element, it is important that +the ($\pm$) state inputs to the solver result in an intermediate state in which the normal components of +velocity vanish. + +Inviscid fluxes (advection terms) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The flux for the divergence of the inviscid flux is then calculated with the same numerical +flux function as used in the volume: $\b{h}^*_e = \b{h}_{e}(\b{Q}^-, \b{Q}^+)$. This is +an inviscid-only wall condition, so no section on viscous or gradient fluxes are included +for this particular wall treatment. + +In practice, when the fluid operators in :mod:`~mirgecom.euler`, :mod:`~mirgecom.inviscid`, +:mod:`~mirgecom.viscous` and the forthcoming Compressible Navier-Stokes modules +go to calculate the flux for the divergence of the inviscid transport flux, they call the +`~mirgecom.boundary.FluidBoundary.inviscid_divergence_flux` function, which for this +adiabatic slip boundary, sets the boundary state, $\b{Q}^+$ by calling +:meth:`~mirgecom.boundary.AdiabaticSlipBoundary.adiabatic_slip_state`, and returns the +numerical flux ${h}^*_e = \b{h}_{e}(\b{Q}^-, \b{Q}^+) \cdot \hat{\b{n}}$. + + +Viscous fluxes (diffusion terms) +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The viscous fluxes depend on both the conserved quantities, and their gradient. The gradient +of the conserved quantities is obtained in the solution of the auxiliary equations and the +boundary condition imposed on that system is $\b{Q}_{bc}$. + +The boundary flux for the gradient of the conserved quantities is computed using the same +numerical flux scheme as in the volume: + +.. math:: + + \b{H}^*_s = \b{H}_s(\b{Q}^-, \b{Q}_{bc}) + +The solution of the auxiliary equations yields $\nabla{\b{Q}}^-$, and the gradients for +the species fractions $Y$ and temperature $T$, are calculated using the product rule: + +.. math:: + + \nabla{Y} &= \frac{1}{\rho}\left(\nabla{(\rho{Y})} - Y\nabla{\rho}\right) \\ + \nabla{E} &= \frac{1}{\rho}\left(\nabla{(\rho{E})} - E\nabla{\rho}\right) + +We enforce no penetration for the species fractions by setting: + +.. math:: + + \nabla{Y}^+ = \nabla{Y}^- - \left(\nabla{Y}^-\cdot\hat{\b{n}}\right)~\hat{\b{n}} + +We set the heat flux through the wall to zero by setting: + +.. math:: + + \nabla{T}^+ = \nabla{T}^- - \left(\nabla{T}^-\cdot\hat{\b{n}}\right)~\hat{\b{n}} + +The boundary viscous flux is then calculated using the same flux function as that +in the volume by: + +.. math:: + + h_v^* = \b{h}_v(\b{Q}^-, \b{Q}_{bc}, \nabla{\b{Q}}^-, \nabla{\b{Q}}^+) \cdot \hat{\b{n}} + + +Adiabatic No-slip Wall +---------------------- + +The no-slip boundary condition essentially means that the fluid velocity at the wall +is equal to that of the wall itself: + +.. math:: + \b{v}_{fluid} = \b{v}_{wall} + +For fixed walls, this boundary condition is $\b{v}_{fluid} = 0$. Specifically, this +means the fluid state at the wall for this boundary condition is as follows: + +.. math:: + + \b{Q}_{bc} = \begin{bmatrix}\rho^{-}\\(\rho{E})^{-}\\0\\0\\0\\(\rho{Y})^{-}_{\alpha}\end{bmatrix}, + + +In |mirgecom|, the no-slip boundary condition is enforced weakly by providing the fluxes +at the element boundaries that correpsond to the given boundary condition. For +inviscid fluxes, the numerical flux functions are used with a prescribed boundary +state to get the fluxes. For the viscous fluxes and for the auxilary equation +(i.e. the gradient of the fluid solution), the fluxes are calculated using a +prescribed boundary state that is distinct from the one used for the inviscid flux. + +The following sections describe both the boundary solutions, and the flux functions +used for each step in computing the boundary fluxes for an adiabatic no-slip wall. + +Inviscid fluxes +^^^^^^^^^^^^^^^ + +For the inviscid fluxes, following [Mengaldo_2014]_, Step 1 is to prescribe $\b{Q}^+$ +at the wall and Step 2. is to use the approximate Riemann solver +(i.e. the numerical flux function, $\b{h}_e$) to provide the element flux for the +divergence operator. + +In this section the boundary state, $\b{Q}^+$, used for each no-slip wall is described. +Specifically, we have adiabatic no-slip wall in Step 1a, and an isothermal no-slip wall +in Step 1b. Then the numerical flux calculation is described in Step 2. + +Step 1 $\b{Q}^+$ for adiabatic no-slip +"""""""""""""""""""""""""""""""""""""""" + +For walls enforcing an adiabatic no-slip condition, the boundary state we use for $\b{Q}^+$ is +as follows: + +.. math:: + + \b{Q}^+ = \b{Q}^- - 2(\rho\b{v}^-), + +where $\b{v}^-$ is the fluid velocity corresponding to $\b{Q}^-$.

This ensures that any +Riemann solver used at the boundary will have an intermediate state with 0 velocities on the boundary. +Other choices here will lead to non-zero velocities at the boundary, leading to material penetration +at the wall; a non-physical result. + +.. note:: + + For the adiabatic state, the wall temperature is simply extrapolated from the interior solution and + we use the interior temperature, ${T}_{in}$.
