• Navier–Stokes equationsRelated: Its zero-divergence constraint simplifies mass conservation and the momentum equations.

• TurbulenceCompared with: Many classic turbulence models assume this simpler flow regime.

• Continuity equationCompared with: Its simplified continuity condition contrasts with the general density-dependent equation.

• Fluid mechanicsBroader topic: It is a useful approximation for many liquid flows and low-speed gas flows.

• Bernoulli's principleRelated: This assumption simplifies the energy relation, especially for liquids and low-speed air.

• DivergenceRelated: Its velocity field has zero divergence.

• Fluid dynamicsBroader topic: It is a widely used simplification for liquids and low-speed gas flows.

• Potential flowRelated: Together with irrotationality, incompressibility makes the potential harmonic.

• Compressible flowCompared with: It is the limiting approximation that compressible-flow analysis replaces when density changes matter.

• Venturi effectRelated: The simplest Venturi relation assumes density does not change along the passage.

• Euler equationsCompared with: Its constraint simplifies the Euler system and changes how pressure is determined.

• Rayleigh–Taylor instabilityRelated: Many classic treatments assume this limit to isolate interface dynamics.

• StreamlineRelated: In this common setting, streamline spacing helps indicate changes in flow speed.

• Kelvin–Helmholtz instabilityRelated: Many classic treatments assume incompressibility to isolate shear-driven wave growth.

• StreamliningRelated: Many ordinary vehicle and swimming flows are analyzed under this approximation.

• Steady flowRelated: Steady flow concerns time variation; incompressibility is a separate property that can accompany it.

• Claude-Louis NavierRelated: This common restriction simplifies the equations associated with Navier’s work.

• Kutta–Joukowski theoremRelated: The standard theorem assumes density can be treated as uniform and constant.

• SourceCompared with: Its local volume preservation rules out velocity-field sources.

• Solenoidal vector fieldRelated: For constant-density flow, incompressibility requires the velocity field to be solenoidal.

• Helmholtz decompositionRelated: Its velocity field already satisfies the divergence-free condition of one component.

• Rayleigh–Plesset equationRelated: The classical equation assumes liquid incompressibility, limiting its validity during rapid collapse.

• Hele-Shaw cellRelated: This condition helps make the depth-averaged velocity field divergence-free.

• Low Reynolds number flowRelated: Many canonical low-Reynolds-number models assume incompressibility.

• Taylor–Proudman theoremRelated: Incompressibility combines with the force balance to constrain axial velocity variation.
