section{Discretization Schemes}
In order for computational fluid dynamics simulations cite{robbins2010fundamentals} (CFD) we need discretization schemes which take partial differential equations (PDEs) from continuous equations which represent physical phenomena into discrete equations which can be solved numerically. In this section we will introduce three different discretization methods used throughout this dissertation; finite difference method (FDM), finite volume method (FVM) cite{patankar1980numerical}, finite element method (FEM). These methods have been chosen due their popularity within CFD; FDM was used extensively during early CFD development while FVM is currently more commonly used cite{robbins2010fundamentals}. FEM has been chosen due its versatility when dealing with complex geometries cite{bathe2006finite}.
subsection{Finite Difference Method}
FDM uses Taylor series expansions cite{abramowitz1965handbook} around grid points which allows PDEs expressed in terms of partial derivatives cite{johnson2011introduction} be expressed in terms of finite differences between grid points which can be solved numerically cite{patankar1980numerical}. For example let us consider an arbitrary function $u(x)$ whose derivative $u'(x)$ we wish to calculate at point $x_i$. We can use Taylor series expansion around point $x_i$ cite{abramowitz1965handbook} which gives
begin{equation}
u(x_{i+1}) = u(x_i) + u'(x_i)(x_{i+1} - x_i) + frac{u''(x_i)}{2}(x_{i+1} - x_i)^2 + ...
end{equation}
and
begin{equation}
u(x_{i-1}) = u(x_i) - u'(x_i)(x_i - x_{i-1}) + frac{u''(x_i)}{2}(x_i - x_{i-1})^2 - ...
end{equation}
If we subtract equation (refeqn:eqn:fdm:eqn_1b) from equation (refeqn:eqn:fdm:eqn_1a) we get
begin{equation}
u(x_{i+1}) - u(x_{i-1}) = u'(x_i)(x_{i+1} - x_{i-1}) + frac{u''(x_i)}{2}(x_{i+1} - x_{i-1})^2 + ...
end{equation}
We can then rearrange this equation such that
begin{equation}
u'(x_i) = frac{(u(x_{i+1}) - u(x_{i-1}))}{(x_{i+1} - x_{i-1})} + frac{(u''(x_i))}{2}(x_{i+1} - x_{i-1}) + ...
label{eqn:fdm:eqn_2}
end{equation}
If we assume that $(x_{i+1} - x_i) = (x_i - x_{i-1}) = h$ then equation (refeqn:eqn:fdm:eqn_2) becomes
begin{equation}
u'(x_i) = frac{(u(x_{i+1}) - u(x_{i-1}))}{(2h)} + O(h^2)
end{equation}
which is known as central difference scheme which approximates $u'(x)$ at point $x_i$ using two neighbouring points $x_{i-1}$ and $x_{i+1}$.
If we expand equation (refeqn:eqn:fdm:eqn_1a) about point $x_{i+1}$ instead such that
begin{equation}
u(x_i) = u(x_{i+1}) - u'(x_{i+1})(x_i - x_{i+1}) + frac{u''(x_{i+1})}{2}(x_i - x_{i+1})^2 + ...
end{equation}
and rearrange such that
begin{equation}
u'(x_{i+1}) = frac{(u(x_{i+1}) - u(x_i))}{(x_{i+1} - x_i)} + frac{(u''(x_{i+1}))}{2}(x_{i+1} - x_i) + ...
label{eqn:fdm:eqn_4}
end{equation}
then if we assume $(x_{i+1} - x_i) = h$ then equation (refeqn:eqn:fdm:eqn_4) becomes
begin{equation}
u'(x_{i+1}) = frac{(u(x_{i+1}) - u(x_i))}{(h)} + O(h)
end{equation}
which is known as forward difference scheme which approximates $u'(x)$ at point $x_{i+1}$ using two neighbouring points $x_i$ and $x_{i+1}$.
Similarly if we expand equation (refeqn:eqn:fdm:eqn_1b) about point $x_{i-1}$ such that
begin{equation}
u(x_i) = u(x_{i-1}) + u'(x{i-1})(x_i - x{i-1}) + frac{u''(x{i-1})}{2}(x_i - x{i-1})^2 + ...
end{equation}
and rearrange such that
begin{equation}
u'(x{i-1}) = frac{(u(x{i}) - u(x{i-1}))}{(xi-x{i-1}} + frac{(u''(xi))}{2}(xi-x{i-1}} + ...
label{eqn:fdm:eqn_6}
end{equation}
then if we assume $(xi-x{i-1}} = h$ then equation (refeqn:eqn:fdm:eqn_6) becomes
begin{equation}
u'(xi{-}l{-}l)=\
=frac{(ui{-}ui{-}l)}{(hl)} + O(h)
end{equation}
which is known as backward difference scheme which approximates $u'(xi)$ at point $xi{-}l{-}l$ using two neighbouring points xi{-}l{-}l$ and xi{-}l.
The central difference scheme gives us second order accuracy while forward or backward difference schemes give us first order accuracy since they include first order error terms. In general second order accuracy will be better than first order accuracy but second order schemes may not be possible if we only have one sided information.
The above examples were shown using Taylor series expansions about single points but this approach can be extended by expanding about multiple points such as four points shown below:
begin{align*}
f(i)&=f(i)+f^{'}(j)(j-i)+f^{''}(j)(j-i)^2/2!\
&+ldots+f^{m}(j)(j-i)^m/m!+ldots\
f(j)&=f(j)+f^{'}(k)(k-j)+f^{''}(k)(k-j)^2/2!\
&+ldots+f^{m}(k)(k-j)^m/m!+ldots\
f(k)&=f(k)+f^{'}(l)(l-k)+f^{''}(l)(l-k)^2/2!\
&+ldots+f^{m}(l)(l-k)^m/m!+ldots\
f(l)&=f(l)+f^{'}(m)(m-l)+f^{''}(m)(m-l)^2/2!\
&+ldots+f^{m}(m)(m-l)^m/m!+ldots
end {align*}
The above equations can be rearranged into matrix form such that
$$A(f(i), f(j), f(k), f(l))=B(f^{'}(j), f^{''}(j), f^{''' }(j), f^{iv }(j), f(v')(k), ... )$$
where A contains coefficients from Taylor series expansions while B contains derivatives at points j,k,l,m.
This system of equations can then be solved using Gaussian elimination or other techniques once boundary conditions have been applied.
FDM has several advantages over other discretization methods including simplicity since it does not require complex geometric considerations unlike FEM or FVM; ease-of-use since it is relatively easy for programmers unfamiliar with numerical methods; speed since it requires less computational resources compared with FEM or FVM; accuracy since it provides accurate results even when grid spacing is large compared with other methods; flexibility since it allows user-defined boundary conditions unlike other methods which may require specific boundary conditions; generality since it applies equally well regardless whether problem domain consists solely spatial dimensions or includes temporal dimension(s).
However there are also some disadvantages associated with FDM including lack-of-flexibility since only certain types problems can be solved using this method (e.g., problems involving complex geometries); difficulty handling irregular domains since grid spacing must remain constant throughout domain; difficulty handling moving boundaries since new grids must be generated every time boundary moves; difficulty handling non-linear problems since nonlinear terms must be linearized before solving system equations; difficulty handling problems involving multiple dimensions since multiple grids must be generated simultaneously; difficulty handling problems involving time-dependence since new grids must be generated every time step taken.
In conclusion FDM provides an efficient way solve partial differential equations numerically however there are limitations associated with this method which must considered when choosing appropriate discretization technique for particular application.
