Question
What is the pressure drop that arises from a Lid-driven cavity flow?
Expert Solution
Step 1
A Lid-driven cavity flow refers to the motion of a fluid contained within a square or rectangular cavity where one of the walls is being moved or "driven" by an external force.
In general, as the speed of the lid increases, the pressure within the cavity will decrease. This is due to the increase in velocity and shear forces at the moving wall, which cause the fluid to accelerate and generate a region of low pressure near the lid. The magnitude of the pressure drop will depend on various factors, including the viscosity of the fluid, the size and shape of the cavity, the lid speed, and the Reynolds number of the flow.
