Numerical simulation of gas jet in liquid crossflow with high mean jet to crossflow velocity ratioRek, Zlatko ...A jet in crossflow (JiCF) is a type of flow found in several important industrial applications. A gas jet in liquid crossflow represents one of the possible configurations for which there are fewer ... published studies than for other types of JiCF. The aim of this paper was to determine the equations for the gas jet trajectory and deflection angle via numerical experiments. A three-dimensional numerical simulation of a turbulent two-phase time-dependent flow was conducted with OpenFOAM to obtain the necessary data. Following computational fluid dynamics, the numerical model was validated against experimental data. The agreement between the calculated and measured results was good. The numerical simulation results demonstrated that the jet centerline trajectory could be described by a power regression curve whose coefficient and exponent depended on the liquid Reynolds number. A similar correlation, but with a constant coefficient and exponent, was obtained for the jet deflection angle. Both proposed correlations were valid for a wide range of liquid Reynold numbers, constant high mean jet-to-crossflow velocity ratios, and low jet-to-crossflow density ratios.Source: Chemical Engineering Science. - ISSN 0009-2509 (Vol. 172, Nov. 2017, str. 667-676)Type of material - article, component partPublish date - 2017Language - englishCOBISS.SI-ID - 15594779
