  • Boundary Layer Separation

    Boundary Layer Separation

    BOUNDARY LAYER SEPARATION When fluid flows past a body (cylinder or an aeroplane), fluid is accelerated due to pressure drop and ∂p/∂x is negative (pressure decreases as x increases). When ∂p/∂x becomes zero, velocity decreases and separation of flow occurs and back flow is just to start. At the point of separation, the following are […]
