The Boussinesq hypothesis states that density variations in a fluid can be considered negligible except when they affect buoyancy. This simplification is especially useful in fluid dynamics, particularly when analyzing flows where temperature differences lead to density changes, such as in natural convection. By focusing on buoyancy and disregarding other density effects, the Boussinesq hypothesis allows for a more manageable set of equations while still capturing the essential physics of the flow.
congrats on reading the definition of Boussinesq Hypothesis. now let's actually learn it.
