Despite the scarcity of data available to treat choking velocity in vertical air-solid two-phase flow, an attempt is made to obtain the characteristics of choking velocity by using experimental results which cover a wide range of particle characteristics and pipe inner diameters. New correlations ...
sideswipe the metal droplet surface that melts. Metal atoms fly out liquid surface according to certain way form the atom cluster by the condensing of inert air current, merger and the collision between crystal nucleus pellet and atom cluster form the smoke flame of nanoparticle pellet eventually....
air velocities in heat exchanging pipes were respectively 0.6 m/s,1.0 m/s,1.5 m/s,2.0 m/s,2.5 m/s and 2.8 m/s during heating at night after heat saving in clear days.The power for heating was enhanced with the increase of the air velocity in heat exchanging pipes.The average power...
(Astronautics) the ratio of the thrust produced by a rocket engine to the rate of fuel consumption: it has units of time and is the length of time that unit weight of propellant would last if used to produce one unit of thrust continuously ...
Thermal comfort of room occupants is essentially influenced by the airflow velocities. Mean velocity of airflow drafted toward people normally should not exceed 0.25m/s, otherwise draft dissatisfaction will arise[19]. Seen fromTable 2, plane averaged air flow intensity in the cross plane (worst ...

Development of co-current air–water flow in a vertical pipe Measurements of the cross-sectional distribution of the gas fraction and bubble size distributions were conducted in a vertical pipe with an inner diameter... KM Prasser - 《International Journal of Multiphase Flow》 被引量: 95发表: ...
Air and nitrogen gas was used in a cooling box to restore the ambient temperature on the damper before a new test. Temperature increases were recorded for each test. The maximum increase took place at the end of the test velocity variation B, with 40°C recorded from the sensor installed ...
