The present article delves into the comprehensive study of internal flow dynamics within a cryogenic chamber used for freezing food with high water percent. For cryogenic freezing is necessary to reduce temperature extremely and maintain a uniform distribution, different behaviours may cause structural damages on food. This is because the chamber comprises a circular-sectioned tunnel or chamber coupled with a set of Jet-type atomizers for the injection of liquid nitrogen. The internal flow, predominantly consisting of liquid nitrogen, necessitates prolonged residency within the chamber to uniformly and effectively cool or freeze food traversing its interior. Consequently, the primary aim is to extend the cryogenic fluid's residence time, achieved by strategically decelerating the flow. This deceleration is orchestrated through the strategic injection of the fluid to induce a swirling or ...
