    The third case is referred to as three-dimensional mixed convection. This flow occurs when the buoyant motion acts perpendicular to the forced motion. An example of this case is a hot, vertical flate plate with a horizontal flow, e.g. the surface of a solar thermal central receiver.

  4. Forced convection - Wikipedia

    en.wikipedia.org/wiki/Forced_convection

    Forced convection is a mechanism, or type of transport, in which fluid motion is generated by an external source (like a pump, fan, suction device, etc.). Alongside natural convection , thermal radiation , and thermal conduction it is one of the methods of heat transfer and allows significant amounts of heat energy to be transported very ...

  5. Sediment transport - Wikipedia

    en.wikipedia.org/wiki/Sediment_transport

    The location in the flow in which a particle is entrained is determined by the Rouse number, which is determined by the density ρ s and diameter d of the sediment particle, and the density ρ and kinematic viscosity ν of the fluid, determine in which part of the flow the sediment particle will be carried. [19]

    An example is the Pleistocene Epoch ... Not to be confused with concretion. ... The current moves because it has a higher density than the fluid through which it flows.

  7. Fault zone hydrogeology - Wikipedia

    en.wikipedia.org/wiki/Fault_zone_hydrogeology

    Fault zone hydrogeology is the study of how brittlely deformed rocks alter fluid flows in different lithological settings, such as clastic, igneous and carbonate rocks. [1] Fluid movements, that can be quantified as permeability , can be facilitated or impeded due to the existence of a fault zone . [ 1 ]

  8. Outline of fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Outline_of_fluid_dynamics

    In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).

  9. Convection (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Convection_(Heat_transfer)

    Familiar examples are the upward flow of air due to a fire or hot object and the circulation of water in a pot that is heated from below. Forced convection : when a fluid is forced to flow over the surface by an internal source such as fans, by stirring, and pumps, creating an artificially induced convection current.
