\section{Description of the computation}
|
||||||
|
\subsection{Irreversible equation}
|
||||||
|
\indent Consider the {\it irreversible} Navier-Stokes equation in 2 dimensions
|
||||||
|
\begin{equation}
|
||||||
|
\partial_tu=\nu\Delta u+g-\nabla w-(u\cdot\nabla)u,\quad
|
||||||
|
\nabla\cdot u=0
|
||||||
|
\label{ins}
|
||||||
|
\end{equation}
|
||||||
|
in which $g$ is the forcing term and $w$ is the pressure.
|
||||||
|
We take periodic boundary conditions, so, at every given time, $u(t,\cdot)$ is a function on the unit torus $\mathbb T^2:=\mathbb R^2/\mathbb Z^2$. We represent $u(t,\cdot)$ using its Fourier series
|
||||||
|
\begin{equation}
|
||||||
|
\hat u_k(t):=\int_{\mathbb T^2}dx\ e^{2i\pi kx}u(t,x)
|
||||||
|
\end{equation}
|
||||||
|
for $k\in\mathbb Z^2$, and rewrite~\-(\ref{ins}) as
|
||||||
|
\begin{equation}
|
||||||
|
\partial_t\hat u_k=
|
||||||
|
-4\pi^2\nu k^2\hat u_k+\hat g_k-2i\pi k\hat w_k
|
||||||
|
-2i\pi\sum_{\displaystyle\mathop{\scriptstyle p,q\in\mathbb Z^2}_{p+q=k}}
|
||||||
|
(q\cdot\hat u_p)\hat u_q
|
||||||
|
,\quad
|
||||||
|
k\cdot\hat u_k=0
|
||||||
|
\label{ins_k}
|
||||||
|
\end{equation}
|
||||||
|
We then reduce the equation to a scalar one, by writing
|
||||||
|
\begin{equation}
|
||||||
|
\hat u_k=\frac{2i\pi k^\perp}{|k|}\hat\varphi_k\equiv\frac{2i\pi}{|k|}(-k_y\hat\varphi_k,k_x\hat\varphi_k)
|
||||||
|
\end{equation}
|
||||||
|
in terms of which, multiplying both sides of the equation by $\frac{k^\perp}{|k|}$,
|
||||||
|
\begin{equation}
|
||||||
|
\partial_t\hat \varphi_k=
|
||||||
|
-4\pi^2\nu k^2\hat \varphi_k+\frac{k^\perp}{2i\pi|k|}\cdot\hat g_k
|
||||||
|
-\frac{2i\pi}{|k|}\sum_{\displaystyle\mathop{\scriptstyle p,q\in\mathbb Z^2}_{p+q=k}}
|
||||||
|
(q\cdot p^\perp)(k^\perp\cdot q^\perp)\hat\varphi_p\hat\varphi_q
|
||||||
|
\label{ins_k}
|
||||||
|
\end{equation}
|
||||||
|
which, since $q\cdot p^\perp=q\cdot(k^\perp-q^\perp)=q\cdot k^\perp$, is
|
||||||
|
\begin{equation}
|
||||||
|
\partial_t\hat \varphi_k=
|
||||||
|
-4\pi^2\nu k^2\hat \varphi_k+\frac{k^\perp}{2i\pi|k|}\cdot\hat g_k
|
||||||
|
+\frac{4\pi^2}{|k|}\sum_{\displaystyle\mathop{\scriptstyle p,q\in\mathbb Z^2}_{p+q=k}}
|
||||||
|
(q\cdot k^\perp)(k\cdot q)\frac{\hat\varphi_p\hat\varphi_q}{|p||q|}
|
||||||
|
.
|
||||||
|
\label{ins_k}
|
||||||
|
\end{equation}
|
||||||
|
We truncate the Fourier modes and assume that $\hat\varphi_k=0$ if $|k_1|>K_1$ or $|k_2|>K_2$. Let
|
||||||
|
\begin{equation}
|
||||||
|
\mathcal K:=\{(k_1,k_2),\ |k_1|\leqslant K_1,\ |k_2|\leqslant K_2\}
|
||||||
|
.
|
||||||
|
\end{equation}
|
||||||
|
\bigskip
|
||||||
|
|
||||||
|
\point{\bf FFT}. We compute the last term in~\-(\ref{ins_k})
|
||||||
|
\begin{equation}
|
||||||
|
T(\hat\varphi,k):=
|
||||||
|
\sum_{\displaystyle\mathop{\scriptstyle p,q\in\mathbb Z^2}_{p+q=k}}
|
||||||
|
\frac{\hat\varphi_p}{|p|}
|
||||||
|
(q\cdot k^\perp)(k\cdot q)\frac{\hat\varphi_q}{|q|}
|
||||||
|
\end{equation}
|
||||||
|
using a fast Fourier transform, defined as
|
||||||
|
\begin{equation}
|
||||||
|
\mathcal F(f)(n):=\sum_{m\in\mathcal N}e^{-\frac{2i\pi}{N_1}m_1n_1-\frac{2i\pi}{N_2}m_2n_2}f(m_1,m_2)
|
||||||
|
\end{equation}
|
||||||
|
where
|
||||||
|
\begin{equation}
|
||||||
|
\mathcal N:=\{(n_1,n_2),\ 0\leqslant n_1\leqslant N_1,\ 0\leqslant n_2\leqslant N_2\}
|
||||||
|
\end{equation}
|
||||||
|
for some fixed $N_1,N_2$. The transform is inverted by
|
||||||
|
\begin{equation}
|
||||||
|
\frac1{N_1N_2}\mathcal F^*(\mathcal F(f))(n)=f(n)
|
||||||
|
\end{equation}
|
||||||
|
in which $\mathcal F^*$ is defined like $\mathcal F$ but with the opposite phase.
|
||||||
|
\bigskip
|
||||||
|
|
||||||
|
\indent The condition $p+q=k$ can be rewritten as
|
||||||
|
\begin{equation}
|
||||||
|
T(\hat\varphi,k)
|
||||||
|
=
|
||||||
|
\sum_{p,q\in\mathcal K}
|
||||||
|
\frac1{N_1N_2}
|
||||||
|
\sum_{n\in\mathcal N}e^{-\frac{2i\pi}{N_1}n_1(p_1+q_1-k_1)-\frac{2i\pi}{N_2}n_2(p_2+q_2-k_2)}
|
||||||
|
\frac{\hat\varphi_p}{|p|}
|
||||||
|
(q\cdot k^\perp)(k\cdot q)\frac{\hat\varphi_q}{|q|}
|
||||||
|
\end{equation}
|
||||||
|
provided
|
||||||
|
\begin{equation}
|
||||||
|
N_i>4K_i.
|
||||||
|
\end{equation}
|
||||||
|
Indeed, $\sum_{n_i=0}^{N_i}e^{-\frac{2i\pi}{N_i}n_im_i}$ vanishes unless $m_i=0\%N_i$ (in which $\%N_i$ means `modulo $N_i$'), and, if $p,q\in\mathcal K$, then $|p_i+q_i|\leqslant2K_i$. Therefore,
|
||||||
|
\begin{equation}
|
||||||
|
T(\hat\varphi,k)
|
||||||
|
=
|
||||||
|
\frac1{N_1N_2}
|
||||||
|
\mathcal F^*\left(
|
||||||
|
\mathcal F(|p|^{-1}\hat\varphi_p)(n)
|
||||||
|
\mathcal F((|q|^{-1}(q\cdot k^\perp)(k\cdot q)\hat\varphi_q)_q)(n)
|
||||||
|
\right)(k)
|
||||||
|
\end{equation}
|
||||||
|
which we expand
|
||||||
|
\begin{equation}
|
||||||
|
T(\hat\varphi,k)
|
||||||
|
=
|
||||||
|
\textstyle
|
||||||
|
\frac{k_x^2-k_y^2}{N_1N_2}
|
||||||
|
\mathcal F^*\left(
|
||||||
|
\mathcal F\left(\frac{\hat\varphi_p}{|p|}\right)(n)
|
||||||
|
\mathcal F\left(\frac{q_xq_y}{|q|}\hat\varphi_q\right)(n)
|
||||||
|
\right)(k)
|
||||||
|
-
|
||||||
|
\frac{k_xk_y}{N_1N_2}
|

\mathcal F^*\left(
|
