  2. Reverse-flow cylinder head - Wikipedia

    en.wikipedia.org/wiki/Reverse-flow_cylinder_head

    This means that the generally inferior flow of a reverse-flow head is less of a disadvantage. In the early days of turbo charging a reverse-flow head allowed the compressor outlet of a turbocharger to blow directly into the inlet manifold with either a blow-through or draw-through carburettor and no intercooler. This allowed the use of shorter ...

  3. Boundary conditions in fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Boundary_conditions_in...

    Showing outlet flow velocity in a pipe. In outlet boundary conditions, the distribution of all flow variables needs to be specified, mainly flow velocity. This can be thought as a conjunction to inlet boundary condition. This type of boundary conditions is common and specified mostly where outlet velocity is known. [1]

  4. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    [4] [5] [6] A generalized model of the flow distribution in channel networks of planar fuel cells. [6] Similar to Ohm's law, the pressure drop is assumed to be proportional to the flow rates. The relationship of pressure drop, flow rate and flow resistance is described as Q 2 = ∆P/R. f = 64/Re for laminar flow where Re is the Reynolds number.

  5. Flow separation - Wikipedia

    en.wikipedia.org/wiki/Flow_separation

    The fluid exerts a constant pressure on the surface once it has separated instead of a continually increasing pressure if still attached. [4] In aerodynamics, flow separation results in reduced lift and increased pressure drag, caused by the pressure differential between the front and rear surfaces of the object. It causes buffeting of aircraft ...

  6. Compressor characteristic - Wikipedia

    en.wikipedia.org/wiki/Compressor_characteristic

    Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor.It shows changes in fluid pressure, temperature, entropy, flow rate etc.) with the compressor operating at different speeds.

  7. Reversible process (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Reversible_process...

    The dependence of work on the path of the thermodynamic process is also unrelated to reversibility, since expansion work, which can be visualized on a pressure–volume diagram as the area beneath the equilibrium curve, is different for different reversible expansion processes (e.g. adiabatic, then isothermal; vs. isothermal, then adiabatic ...

  8. Schlieren photography - Wikipedia

    en.wikipedia.org/wiki/Schlieren_photography

    The process works by imaging the deflections of light rays that are refracted by a moving fluid, allowing normally unobservable changes in a fluid's refractive index to be seen. [1] Because changes to flow rate directly impact the refractive index of a fluid, one can therefore photograph a fluid's flow rate (as well as other changes to density ...

  9. Radial piston pump - Wikipedia

    en.wikipedia.org/wiki/Radial_piston_pump

    The piston starts in the inner dead center (IDC) with suction process. After a rotation angle of 180° it is finished and the workspace of the piston is filled with the moved medium. The piston is now in the outer dead center (ODC). From this point on the piston displaces the previously sucked medium in the pressure channel of the pump.
