- Abstract
- As the first stage in a long-range investigation of the complex coupling of aerodynamics and chemical heat release which occurs in chemically reacting turbulent flows, we have initiated an investigation of the effects on turbulent mixing of density differences between a simple gas jet and the surrounding gas. We have recently shown that laser-induced Rayleigh light scattering can be used as a simple diagnostic for absolute measurements of concentration in simple flow systems of two different gases. This technique is capable of high spatial and temporal resolution.
