Assessment of condensation models for moist air transonic flow prediction
نویسندگان
چکیده
The aim of this article is to thoroughly analyse the influence condensation models on modelling phenomena in transonic flow moist air. reason for study was fact that different are used by researchers obtain satisfactory results numerical modelling. tested herein differ nucleation rate formula and droplets growth equation. Four most often were selected detailed investigations. obtained from each model compared with experiments nozzle flow. main focus location onset process. Moreover, intensity discussed. CFD calculations performed using ANSYS Fluent commercial tool. Finally, which suitable air recommended.

Aerosol Atomization from Transonic Air Jets in Cross Flow
We investigate the droplet size distributions and concentrations produced by an aerosol generator driven by a high velocity air jet delivered in cross flow to an oil tube at Mach numbers of 0.1-1.0, and Weber numbers based on the air flow parameters between 1000 to 40000. Measured Sauter mean droplet diameters (SMD) from 1μm to 3.5μm were determined by an Electronic Low Pressure Impactor over t...
متن کاملStatus and preparation of prediction models for ozone as an air pollutant in Shiraz, Iran
In the present study, air quality analyses for ozone (O3) were conducted in Shiraz, a city in the south of Iran. The measurements were taken from 2011 through 2012 in two different locations to prepare average data in the city. The average concentrations were calculated for every 24 hours, each month and each season. Results showed that the highest concentration of ozone occurs generally in the...
