			In [[fluid dynamics]], the '''Boussinesq approximation''' ({{IPA-fr\|businɛsk\|pron}}, named for [[Joseph Valentin Boussinesq]]) is used in the field of buoyancy-driven flow (also known as [[natural convection]]). It states that density differences are sufficiently small to be neglected, except where they appear in terms multiplied by ''g'', the acceleration due to gravity. The essence of the [[Valentin Joseph Boussinesq\|Boussinesq]] approximation is that the difference in [[inertia]] is negligible but gravity is sufficiently strong to make the specific [[weight]] appreciably different between the two fluids. [[sound\|Sound waves]] are impossible/neglected when the Boussinesq approximation is used since sound waves move via density variations.

			Boussinesq flows are common in nature (such as [[surface weather analysis\|atmospheric front]]s, oceanic circulation, [[katabatic wind]]s), industry ([[Air pollution dispersion terminology\|dense gas dispersion]], fume cupboard ventilation), and the built environment (natural ventilation, [[central heating]]). The approximation is extremely accurate for many such flows, and makes the mathematics and physics simpler.

			The approximation's advantage arises because when
			considering a flow of, say, warm and cold water of density
			<math>\rho_1</math> and <math>\rho_2</math> one needs only consider a
			single density <math>\rho</math>: the difference

			[[Dimensional analysis]] shows that, under these circumstances, the only sensible

			(Note that the denominator may be either density without affecting the result because the change would be of order
			<math>g(\Delta\rho/\rho)^2</math>). The most generally used [[dimensionless number]] would be the [[Richardson number]] and [[Rayleigh number]].

			The mathematics of the flow is therefore simpler because the density ratio (<math>\rho_1/\rho_2</math>, a [[dimensionless number]]) does not affect the flow; the Boussinesq approximation states that it may be assumed to be exactly one.

			==Inversions==

			One feature of Boussinesq flows is that they look the same when viewed upside-down, provided that the identities of the fluids are reversed. The Boussinesq approximation is ''inaccurate'' when the nondimensionalised density difference <math>\Delta\rho/\rho</math> is of order unity.

			For example, consider an open window in a warm room. The warm air inside is lighter than the cold air outside, which flows into the room and down towards the floor. Now imagine the opposite: a cold room exposed to warm outside air. Here the air flowing in moves up toward the ceiling. If the flow is Boussinesq (and the room is otherwise symmetrical), then viewing the cold room upside down is exactly the same as viewing the warm room right-way-round. This is because the only way density enters the problem is via the reduced gravity <math>g'</math> which undergoes only a sign change when changing from the warm room flow to the cold room flow.

			An example of a non-Boussinesq flow is bubbles rising in water. The behaviour of air bubbles rising in water is very different from the behaviour of water falling in air: in the former case rising bubbles tend to form hemispherical shells, while water falling in air splits into raindrops (at small length scales [[surface tension]] enters the problem and confuses the issue).
