To make things even more complex another type of averaging often used is flux-averaging. With flux-averaging all gradients are mixed out and a flux-averaged value is the value you would get if you measure at the outlet of an infinently long friction-free pipe put at the boundary. In turbomachinery applications flux-averaging is common, and sometimes you do not flux-average everything, you do flux-averaging circumferentially to mix-out wakes, but you do not do flux-averaging radially because you do not want to mix-out the end-wall boundary layers.

hello
what do you mean by a conserved variable exactly?
is a scalar transport variable conserved?I have mixed up with a conserved variable and a conserved equation.
thank you.
