Marcello Lappa, in Fluids, Materials and Microgravity, 2004. 2.3.2 Microzone facilities and microscale experimentation. Despite the presence of buoyancy convection that in many cases obscures the Marangoni flow it must be pointed out how some insights into this type of convection can also be obtained by experimental investigation on Earth, if the typical scale of the liquid …
اقرأ أكثرWhen a body rises in a fluid medium, it experiences the external forces of gravity, buoyancy, and fluid drag. The force from gravity is weight (W), and acts downward with magnitude W = mg (m is the mass of the body, and g is the gravitational acceleration, 9.8 m s-2).The buoyancy force (F b) acts upward, opposing gravity.Pressure increases with depth in a fluid medium due to the …
اقرأ أكثرBuoyancy, otherwise called the upthrust, is the force acting in a direction opposite to gravity that prevents a floating object from sinking. When the object is immersed in water (or any other liquid), its weight pulls it downwards. Buoyancy opposes that weight and has a magnitude directly proportional to the volume of fluid that would otherwise occupy the space …

اقرأ أكثرThe resultant force acting on a submerged body by the fluid is called the buoyant force and can be expressed as F = V γ = V ρ g (1) where F = buoyant force (N) V = body volume (m3) γ = ρ g = specific weight of fluid (N/m3) ρ = density of fluid (kg/m3) g = acceleration of gravity (= 9.81 m/s2) The buoyant force acts upwards.

B = (1.161 kg/m3) (9.8 m/s2) (1 m3) B = 11.378 N. The difference in these two forces (buoyancy up minus weight down) is the lifting force described in this problem.
اقرأ أكثرThis effect is termed buoyancy, or buoyant forces. The buoyed weight of the drillstring will be less than the in-air weight of the pipe. Buoyant forces are a function of the volume and weight of the displaced fluid. Heavier muds have greater buoyant forces than low-density muds. The buoyed pipe weight can be calculated from Kq. 18.3:

اقرأ أكثرBuoyancy has its impact in both exchange flow (without imposed velocity) and displacement flow (with imposed velocity). Exchange flow is a convective fluid interpenetration. When buoyancy-induced inertia dominates in an unstable configuration, fluid interface is distorted and not well maintainable, which is R-T instability.
