Dispersive mass transfer — Dispersive mass transfer, in fluid dynamics, is the spreading of mass from highly concentrated areas to less concentrated areas. It is one form of mass transfer. Dispersive mass flux is analogous to diffusion, and it can also be described using… … Wikipedia
Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… … Wikipedia
Convection–diffusion equation — The convection–diffusion equation is a parabolic partial differential equation combining the diffusion equation and the advection equation, which describes physical phenomena where particles or energy (or other physical quantities) are… … Wikipedia
convection — [kən vek′shən] n. [L convectio < pp. of convehere, to bring together < com , together + vehere, to carry, bear] 1. a transmitting or conveying 2. a) the mass movement of parts of a fluid within the fluid because of differences in the… … English World dictionary
Mass–luminosity relation — In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star s mass and its luminosity. The relationship is represented by the equation: where L⊙ and M⊙ are the luminosity and mass of the sun and… … Wikipedia
Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change … Wikipedia
Convective heat transfer — See also: Heat transfer and convection This figure shows a calculation for thermal convection. Colors closer to red are hot areas and colors closer to blue are cold areas. In this figure, a hot, less dense lower boundary layer sends plumes… … Wikipedia
Natural convection — Bénard cells. Natural convection is a mechanism, or type of heat transport, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but only by density differences in the fluid occurring due to… … Wikipedia
Heat transfer coefficient — The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid::Delta Q=h cdot A cdot Delta T cdot Delta… … Wikipedia
Thermomagnetic convection — Ferrofluids can be used to transfer heat, since heat and mass transport in such magnetic fluids can be controlled using an external magnetic field. B. Finlayson first explained in 1970 (in his paper Convective instability of ferromagnetic fluids … Wikipedia
forced convection — noun The convection (carriage) of contents of a fluid, such as mass or (especially) heat, by means of currents induced in the fluid by a force which is not dependent on density changes in the fluid induced by heat. Transfer of heat from the… … Wiktionary
