Question

The upwind scheme is dependent on the _____________

(a) Convection term

(b) Peclet number

(c) Flow direction

(d) Gradient

Answer 1

Right choice is (c) Flow direction

For explanation: The upwind scheme reflects the physics of advection. The cell-face value is dependent on the upwind nodal value. So, we can say it is dependent on the flow direction and it is suitable for directional flows.
