Abstract The onset of turbulence in natural convection systems is difficult to predict using traditional computational techniques. The flow patterns that occur
before and after the onset of turbulence may be better understood with the help of visual techniques like Schlieren imaging. Schlieren imaging allows
visualization of the density gradients of a fluid using collimated light and refractive properties. In this experiment, a device was designed to test the
behavior of airflow with non-isothermal boundary conditions within a rectangular cavity. Previous computational fluid modeling suggested a period
doubling route to chaos in a cavity with a high aspect ratio and free… More >
