Here we will develop a commone definitions and regulations because of

• in different articles was used defferent definitions and notations
• we are searching for common approach and generalisation

## Usual using definition for convected variable

$\boldsymbol{f}$

$\boldsymbol{\phi}$

## definition of considered face, upon wich approximation is applied

usually (in the most articles) west face of the control volume $\boldsymbol{w}$ is considered (without loss of generality)

for which flux is directed from left to the right

we shall define it as $\boldsymbol{f}$

and convected variable at face as $\boldsymbol{\phi_{f}}$
