In this case, the basic stream is encoded into two most significant bits while the secondary stream is encoded into remaining two bits.
At these temperatures, tritium which is a radioactive contaminant found in the reactor coolant stream, is able to contaminate the secondary stream by diffusing through the steel retaining wall of the heat exchanger between the reactor coolant and secondary process coolant stream.
For the ejector under consideration, although global transfers are more important in on-design conditions, it is shown that the net gain in exergy of the secondary stream is maximum for a value of the back pressure that is close to the critical back pressure, as irreversibilities due to viscous dissipation are significantly lowered compared to other operating points.
The presence of this 2-D film layer helps minimize the rate of mixing between the main and the secondary streams.
In addition to this topological approach, an analysis based on classical stream tubes is performed in order to quantitatively investigate transfers between the primary and the secondary streams all along the ejector.
This gives Facebook's button a distinct advantage over Twitter's, as the action of following someone through Twitter's button doesn't appear in the main tweet stream, only a secondary stream.
There are reasonable prospects for the development of reliable engineering models for secondary stream entrainment in ejector applications based on existing correlations for compressible mixing.
Evaporative cooler: Type 757a Model an evaporative cooling device for which the user supplies the inlet air conditions of a primary and secondary air stream and the device effectiveness as a function of primary stream inlet air dry bulb temperature and secondary stream inlet air wet bulb temperature.
Independently, IMAGE/LENA has reported neutral atom observations that may be interpreted as a "secondary stream" having different characteristics and flowing from a higher ecliptic longitude than the nominal upstream direction.
Most groups coped with the desert environment by occupying sites on waterways; these ranged in quality and reliability from large permanent rivers such as the Colorado, through secondary streams, to washes or gullies that channeled seasonal rainfall but were dry most of the year.
