The remaining part of the total thrust is derived from the core stream, which is exhausted through a jet nozzle.
The core stream, with some modest fraction of the gas horsepower remaining (not extracted to drive the fan) proceeds directly to its own exhaust nozzle.
Gmail's new approach resembles, in a way, Facebook's revamped Timeline, the social network's attempt to make its core stream more manageable by dividing it into disparate parts.
The afterburner in a turbofan usually requires a mixer for mixing the relatively cool bypass air with the hot core stream (see Figure 6); the cooler air is otherwise difficult to burn in the low-pressure environment of an afterburner.
The viscosity ratio of the core stream to the sheathing stream ranged between 0.14 to 5.22.
The expressions are proposed for the expanding length and the diameter of the core stream.
The high velocity annular stream was found to quickly diffuse after entering through the chutes and mix with the core stream due to higher levels of turbulence generated in the mixing region.
A series of solutions of glycerol in deionized water with various viscosities (35.49 mPa·s 1311.15 mPa·s) were used as the core stream, and the ionic liquid ([BMIM][PF6]) (251.76 mPa·s) was used as the sheathing stream.
The effects of the flow rate ratio and the viscosity ratio of both phases, and the capillary number of the core stream on the characterized size of the core-annular flow were studied.
To demonstrate the various applications of the paper capillary force driven hollow channel, several devices are design and made to complete the purpose of exhibiting laminar flow in a T-junction microchannel, sheath a core stream in a three-inlet channel and transportation whole blood.
