Professor Longmire’s research uses advanced experimental methods to study single- and multi-phase turbulent flows, liquid/liquid mixtures, microscale flows, and biomedical flows. Current projects focus on eddy identification and particle transport in turbulent boundary layers, how discrete particles affect transition to turbulence, liquid/liquid flows with contact effects, and spray deposition of cells.
