# Approximation Schemes for convective term - structured grids - definitions

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 considered the face

$\boldsymbol{w}$

for which flux is directed from left to the right
