Test Case

Laminar flow of a fluid over an inclined plane, driven by the pressure difference due to gravity head is modeled. The flow channel is inclined at an angle β = 30° with the horizontal direction.

Material Properties

Geometry

Boundary Conditions

Density = 800 kg/m³

Viscosity = 1 kg/m-s

Dimensions of the domain:

1 m X 18 m

Angle with X-axis = 30°

Gauge Pressure at Inlet = 0 N/m²

Gauge Pressure at Outlet = -706.32 N/m²

Analysis Assumptions and Modeling Notes

The density based solver is used in Ansys Fluent. Pressure boundaries are specified to model the driving head in the direction of flow.
