Vaporization of a liquid hexanes jet in cross flow
چکیده انگلیسی


• The vaporization of a liquid hexanes jet in a lab-scale test section was studied.
• The hexanes vapor concentration increased with the increase of the momentum flux ratio and the supplying air temperature.
• The hexanes vapor concentration was expressed as functions of fuel jet Reynolds number and Weber number.

The vaporization characteristics of a liquid hexanes jet in a lab-scale test section with a plain orifice-type injector were experimentally investigated. The experimental measurements were carried out on the basis of the infrared laser extinction method using two He–Ne lasers (one at 632.8 nm and the other at 3.39 μm). The momentum flux ratio (qF/A) was varied from 20 to 60 over 20 steps, and the supplying air temperature (TA) was changed from 20 to 260 °C over 120 steps. The objectives of the current study were to assess the vaporization characteristics of a liquid hexanes jet and to derive a correlation between flow conditions and hexanes vapor concentration in a jet-in-crossflow configuration. From the results of the experimental measurement, it was concluded that hexanes vapor concentration increased with the increase of the momentum flux ratio and the supplying air temperature. An experimental correlation between flow conditions and hexanes vapor concentration (ZF) was proposed as a function of the normalized horizontal distance (x/do), the supplying air temperature (TA), the momentum flux ratio (qF/A), the fuel jet Reynolds number (ReF), and the fuel jet Weber number (WeF).
