I wanna konw if choosing between first upwinding , or quick , can affect accuracy : error with respect to validated data , i know it affects convergence in residuals .

Yes they affect the quality of the results especially if you are running on coarse grid.

Good reference by the way: https://www.grc.nasa.gov/WWW/wind/valid/tutorial/errors.html

thanks for your generous answer , if i did mesh independent test so it wont affect quality right ?

[DrAmine]

Should not be affected anymore. Actually you need to try to provide a high order solution on an independent grid.
