- Barotropic_fluid abstract "In fluid dynamics, a barotropic fluid is a fluid whose density is a function of only pressure. Barotropic fluids are useful model for fluid behavior in a wide variety of scientific fields, from meteorology to astrophysics.Most liquids have a density which varies weakly with pressure or temperature, i. e., the density of a liquid is nearly constant, so to a first approximation liquids are barotropic. To greater precision, they are not barotropic. For example, the density of seawater depends on temperature, salinity, and pressure, but only by a few percent at most.In astrophysics, barotropic fluids are important in the study of stellar interiors or of the interstellar medium. One common class of barotropic model used in astrophysics is a polytropic fluid. Typically, the barotropic assumption is not very realistic.In meteorology, a barotropic atmosphere is one in which the density depends only on pressure, so that isobaric surfaces (constant-pressure surfaces) are also isopycnic surfaces (constant-density surfaces). The isobaric surfaces will also be isothermal surfaces, hence (from the thermal wind equation) the geostrophic wind is independent of height. Hence the motions of a rotating barotropic air mass or fluid are strongly constrained. The tropics are more nearly barotropic than mid-latitudes because temperature is more nearly horizontally uniform in the tropics.A barotropic flow is a generalization of the barotropic atmosphere. It is a flow in which the pressure is a function of the density only and vice versa. In other words, it is a flow in which isobaric surfaces are isopycnic surfaces and vice versa. One may have a barotropic flow with a non-barotropic fluid, but a barotropic fluid must always follow a barotropic flow. Examples include barotropic layers of the oceans, an isothermal ideal gas or an isentropic ideal gas. A situation which is not barotropic is baroclinic, i. e., pressure is not enough to specify density. For a barotropic fluid or a barotropic flow (such as a barotropic atmosphere), the baroclinic vector is zero.".
