Would you be able to put into plain english what these vector notations mean please.
You can put any meaning you want to the abbreviations (Su, Vf, etc.) - I just want to understand basically what the vector notations mean in plain english.

What is the context?

The context is in relation to flame surfaces.
G is used to define a point on the flame surfact, Vf is the local propagation velocity of the surface and Su is the local flame speed.
It might be easier to picture it in the context of a simple candle flame.

To be honest though you can put it into any context you want to if it makes it easier for you.

A vector is just a magnitude and a direction. V usually means velocity, so the magnitude would be the speed and the direction would be the direction it was heading. (Negative direction basically means it's going in reverse).
To add or subtract vectors if they are going in the same direction you just add or subtract the magnitudes. If there are going different directions then you can figure it by starting one on the end of the other. The sum is the vector from the start of the first one to the end of the last one. (So it looks like a triangle).

Is that what you mean?

And does the tilda and circumflex accent hold any special meaning?

They are just different symbols.
G and G with circumflex are different (but probably related)
There is no standard for what different letters mean. Some are the same in most places, but each university or textbook has its own.

If you just want to know what the tilde and all mean, then you'll have to check with your particular textbook/instructor. There's no common meaning that everyone uses.
