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 ...
Reverse flow may refer to: In engine technology a reverse flow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. Reverse logistics, i.e. goods/waste flowing in the distribution network having consumers as point of origin; Reverse electron flow is a mechanism in microbial metabolism
A significantly different, symmetrical design was adopted for the second model. Ten spiral ducts connected the compressor outlet to a single, large, reverse-flow combustion chamber, the outlet of which discharged forward through the turbine before turning rearwards to exhaust through ten jet pipes.

This includes pressure inlet and outlet conditions mainly. Typical examples that utilize this boundary condition include buoyancy driven flows, internal flows with multiple outlets, free surface flows and external flows around objects. [1] An example is flow outlet into atmosphere where pressure is atmospheric.
The older symbol for this was a small script (italic) f (see herein f). Later the ASA convened upon a letter V (specifically a sans-serif V) touching the surface. Soon this evolved into the "check mark" sign with accompanying number that tells the reader a max roughness value (RMS, microinches or micrometres) for the machined finish, to be ...
[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.
This can occur around cylinders and spheres, for any fluid, cylinder size and fluid speed, provided that the flow has a Reynolds number in the range ~40 to ~1000. [1] In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2]
