{wiki=Adverse_pressure_gradient}
An adverse pressure gradient occurs when pressure increases in the direction of flow. In fluid dynamics, this situation can arise in various contexts, such as in airflow over a surface or in pipe flow. \#\#\# Key Points - **Definition**: An adverse pressure gradient is a condition in which the pressure rises along the flow path, typically causing a deceleration of the fluid flow.
