| Title of the article | Experimental studies of a non-isothermal air jet |
| Abstract. | The calculation of air distribution is one of the most important stages in the design of ventilation and air conditioning systems, the correctness of which largely determines the formation of a comfortable microclimate. Most subject matter experts carry out this calculation using engineering methods. At the same time, the use of methods by different authors leads to very different results. The purpose of the work: based on experimental studies, to determine the most correct method for calculating air distribution by non-isothermal jets supplied horizontally. Research objectives: analysis and comparison of calculation formulas of the most commonly used methods for calculating non-isothermal jets; conducting experimental studies of the supply jet in non-isothermal conditions at the stand of the scientific research laboratory of Aerodynamics and acoustics of the Arktos plant at various parameters at the outlet; comparing the speed, temperature and trajectory of the supply jets with the results of calculations using engineering methods; analysis the results obtained. Based on the conducted research, it was found that none of the generally accepted engineering methods allows correct determination of the parameters of a non-isothermal jet. Therefore, it is necessary to conduct further research and improve methods for calculating air distribution by non-isothermal jets. |
