Velocity Measurement of Air-Water Mixtures

Simultaneous measurement of water flow velocity with fluorescent and speckle imaging technique

The average velocity of water flow has been simultaneously measured with fluorescent and speckle imaging methods. The measured velocities with two methods are in good agreement with each other and it confirms that the speckle imaging method can be used as a confident method to measure the velocity of water flow in a dry leaf. Also the velocity of water flow through thick and thin xylems of a le...

Microbreaking and the enhancement of air-water transfer velocity

[1] The role of microscale wave breaking in controlling the air-water transfer of heat and gas is investigated in a laboratory wind-wave tank. The local heat transfer velocity, kH, is measured using an active infrared technique and the tank-averaged gas transfer velocity, kG, is measured using conservative mass balances. Simultaneous, colocated infrared and wave slope imagery show that wave-rel...

Third Virial Coefficient for Air-Water Vapor Mixtures*

The third interaction virial coefficient Caww for a ir-water vapor mixtures is estimated in the temperature range 0 to 100 °C, by means of an approximate method based on molec ular assoc iation . The res ult s are believed accurate to within a fac tor of two. The value of CawlV can be combined with prev ious es timates of the other interaction coefficient C",m and the values of the third virial...

Water Surface Velocity Measurement Using Pattern Matching Technique

In many cases it is necessary to measure the velocity of water flow whether it is during some installation of scientific research or some natural calamities. But, In surface water studies, it is difficult to measure the velocity of water. Contact Sensors have been used in various examination but they did not execute accurate result. In this paper non-contact velocity measurement technique based...
