Lysak [et al.]. - Текст : непосредственный // Mathematics. - 2023. - Т.11, №13. - P. 3039. - ISSN 2227-7390, DOI 10.3390/math11143039.
Аннотация: The efficiency of annular-nozzle ejectors serving as components of complex technical?systems interacting with high-temperature media in engines and in the field of energy technologies is?not linearly related to the gas-dynamic characteristics of the flows formed in the device. In this paper,we have analyzed the results of numerical and experimental studies of gas jets in an annular-nozzle air ejector. The regression equations built according to the circumscribed central composite design described the relationship between a pressure drop and the structural parameters of the nozzle with the speed and mass flow rates of the airflows, including error rates of no more than 15 percent. A two-factor optimization based on Harington's generalized desirability function was performed to obtain a relatively accurate estimate of the ejector efficiency under the influence of the structural and operating parameters. An optimization method based on the combination of response surface methodology and the desirability function approach, allowing simultaneous consideration of all responses, made it possible to simultaneously optimize multiple conflicting objectives.
