The convective heat transfer enhancement in a turbulent boundary layer (TBL) employing pulsed, slot jet crossflow is investigated experimentally. A parametric study on actuation frequencies and duty cycles performed. actuator flush-mounted that injects fluid into well-behaved zero-pressure-gradient TBL over flat plate. heated-thin-foil sensor measures the time-averaged coefficient downstream of...

An experimental investigation of the primary breakup of nonturbulent round liquid jets in gas crossflow is described. Pulsed shadowgraph and holograph observations of jet primary breakup regimes, conditions for the onset of breakup, properties of waves observed along the liquid surface, drop sue and velocity properties resulting from breakup and conditions required for the breakup of the liquid...

Understanding the trajectory of oil droplets in crossflow jets is important to estimate pathways hydrocarbons and plan countermeasures. We report experimental results an jet with release velocity around 1.5 m/s a 0.3 m/s. The hydrodynamics obtained Large Eddy Simulation (LES) were used predict migration droplets. Two Lagrangian techniques explored, one inertia droplet considered other that trea...
