Similar to aircraft, soaring birds rely upon both speed and lift: speed is caused by gravity as the birds fall towards Earth, and lift is produced by the difference in air pressure flowing over the wing's upper and lower surfaces.
The consistent pattern of vocal fold vibration is a function of muscular tension, the viscoelastic properties of vocal fold tissue, and the air pressure and flow generated by the lungs (23).
As a result, the effect of air pressure on the flow criterion and the flow rate of particles can be evaluated in terms of material properties, vessel geometry and operational conditions.
Spray rate, atomization air pressure, and air flow rate were identified as CPPs.
The factors considered were: (1) rotor disc velocity, (2) gap air pressure, (3) air flow rate, (4) binder spray rate and (5) atomization pressure.
Factors, as substrate temperature, solution concentration, air pressure and precursor flow rate have been studied at two levels.
Experiments were conducted under different practical settings of air pressure, particle mass flow rate and drilling time.
Preliminary hydrodynamic studies indicated that droplet diameter and velocity were strongly dependent on atomizing air pressure and liquid flow rate.
CFD modelling of spray indicates that it is possible to produce aerosol medium with high heat dissipation ability at moderately high air pressure and low flow rate.
Our innovative process enabled us to very rapidly cover textile samples with PLLA nanofibres to determine the influence of air pressure, polymer solution flow rate and polymer concentration on fibre quality.
In addition, the air pressure in cathode flow field of the fuel cell stack and the pressure difference between both sides of proton exchange membrane must be maintained in a certain range during operation.
