Pressure difference on the surface is the difference in pressure between two points on a surface that forms the boundary between two fluid regions. The pressure difference can be caused by various factors, such as the curvature of the surface, the surface tension of the interface, the density and viscosity of the fluids, and the external forces acting on the surface.
- Pressure difference (p − p∞) in N/m^2
- Freestream density (𝜌∞) in kg/m^3
- Freestream velocity (V∞) in m/s
- Angle between a normal to the surface (𝜃) in rad
