Default Order of upwind and blended schemes

Hi everyone,

I was wondering if you could help me confirm a couple of things. I have been trying to verify the order of accuracy of the upwind schemes used in making blended schemes such as the vanleerV.

After searching the forums for a bit I have had the impression that the blended schemes are composed of a second order central scheme and a first order upwind scheme. Is this correct?

I have been tasked with investigating the following term:

div(phi,U) Gauss vanLeerV 1;
and how it is composed. So far I have concluded that it is a blend of a central scheme and an upwind scheme, second and first order respectively. Am I correct in that conclusion?

Does anyone else have some solid references in which I could substantiate this claim?

Thanks in advance.
