Transcritical injection: modeling and experiment*

Transcritical injection presents a challenging problem for numerical modelers because there are multiple physical mechanisms relevant for the interaction of a transcritical jet with crossflow. Along with mechanical jet breakup, heat transfer, interfacial mixing and phase transition also play roles which are not fully understood. We present our progress in developing an experimental framework for a study with the main objective to provide quantitative information about the behavior of the jet that will be used to design and validate a computationally efficient and physically faithful numerical model of the process. The experimental framework will produce benchmarks of increasing complexity, starting with a jet in crossflow without transcritical effects, to make sure that different relevant physics are faithfully modeled.
